Abstract
Two polymorphs and a solvatomorph of a new dimethylammonium polytungstate-decakis(dimethylammonium) dihydrogendodecatungstate, (Me2NH2)10(W12O42)·nH2O (n = 10 or 11)-have been synthesized. Their structures were characterized by single-crystal X-ray diffraction and solid-phase NMR methods. The shape of the dodecatungstate anions is essentially the same in all three structures, their interaction with the cations and water of crystallization, however, is remarkably variable, because the latter forms different hydrogen-bonded networks, and provides a highly versatile matrix. Accordingly, the N-H⋯O and C-H⋯O hydrogen bonds are positioned in each crystal lattice in a variety of environments, characteristic to the structure, which can be distinguished by solid-state 1H-CRAMPS, 13C, 15N CP MAS and 1H-13C heteronuclear correlation NMR. Thermogravimetry of the solvatomorphs also reflect the difference and multiformity of the environment of the water molecules in the different crystal lattices. The major factors behind the variability of the matrix are the ability of ammonium cations to form two hydrogen bonds and the rigidity of the polyoxometalate anion cage. The positions of the oxygen atoms in the latter are favourable for the formation of bifurcated and trifurcated cation-anion hydrogen bonds, some which are so durable that they persist after the crystals are dissolved in water, forming ion associates even in dilute solutions. The H atom involved in furcated hydrogen bonds cannot be exchanged by deuterium when the compound is dissolved in D2O. An obvious consequence of the versatility of the matrix is the propensity of these compounds to form multiple polymorphs.

Abstract
![]()
Chemical transformations
are normally conducted in batch or flow mode, thereby allowing the
chemistry to be temporally or spatially controlled, but these approaches
are not normally combined dynamically. However, the investigation
of the underlying chemistry masked by the self-assembly processes
that often occur in one-pot reactions and exploitation of the potential
of complex chemical systems requires control in both time and space. Additionally, maintaining
the intermediate constituents of a self-assembled system “off
equilibrium” and utilizing them dynamically at specific time
intervals provide access to building blocks that cannot coexist under
one-pot conditions and ultimately to the formation of new clusters.
Herein, we implement the concept of a programmable networked reaction
system, allowing us to connect discrete “one-pot” reactions
that produce the building block{W11O38} ≡
{W11} under different conditions and control, in real time,
the assembly of a series of polyoxometalate clusters {W12O42} ≡ {W12}, {W22O74} ≡ {W22} 1a, {W34O116} ≡ {W34} 2a, and {W36O120} ≡ {W36} 3a, using pH and ultraviolet–visible monitoring. The programmable
networked reaction system reveals that is possible to assemble a range
of different clusters using {W11}-based building blocks,
demonstrating the relationship between the clusters within the family
of iso-polyoxotungstates, with the final structural motif being entirely
dependent on the building block libraries generated in each separate
reaction space within the network. In total, this approach led to
the isolation of five distinct inorganic clusters using a “fixed”
set of reagents and using a fully automated sequence code, rather
than five entirely different reaction protocols. As such, this approach
allows us to discover, record, and implement complex one-pot reaction
syntheses in a more general way, increasing the yield and reproducibility
and potentially giving access to nonspecialists. Here we
describe a programmable networked reaction system connecting reactors
that produce the building block{W11O38} ≡
{W11} under different conditions and control the assembly
of a series of polyoxometalate clusters {W12O42} ≡ {W12}, {W22O74} ≡
{W22} 1a, {W34O116}
≡ {W34} 2a, and {W36O120} ≡ {W36} 3a, using pH and
ultraviolet−visible monitoring. This approach led to the isolation
of five clusters using a fully automated sequence code, rather than
five entirely different reaction protocols.

Abstract
A versatile one-pot strategy was employed to synthesize five cerium(III)-containing polyoxotungstate nanoclusters through pH-controlled and sulfite anion-directed assembly: [C2H8N]3Na7[Ce2(H2O)6W22O72(OH)4]·20H2O (1) at pH 5.0; [C2H8N]8Na16[Ce4(H2O)12W44O144(OH)12]·23H2O (2) at pH 4.5; [C2H8N]2Na4Ce2[Ce2(H2O)10W28O92(OH)2]·27H2O (3) at pH 2.8-3.3; [C2H8N]2Na7[{α-SW7O28}{Ce2(H2O)6}(W3O6){α-SW9O32}{α-SW9O31(OH)}]·18H2O (4) at pH 2.5; [C2H8N]2Na18[Ce2(H2O)9W36O110(OH)12]2·30H2O (5) at pH 1.5. These compounds were characterized by single-crystal X-ray structure analysis, IR spectroscopy, thermogravimetric (TG) analysis, X-ray photoelectron spectroscopy (XPS), and electrospray ionization mass spectrometry (ESI-MS). Moreover, their electrochemical properties were investigated. Single-crystal X-ray structure analysis revealed that 1 and 2 were di- and tetra-cerium(III)-bridged polyoxotungstates, constructed from two different types of lacunary {W11} units. 3 composed of the well-known cerium(III)-stabilized {W28} unit and organic amine-sodium-cerium cations, was isolated in the pH range 2.8-3.3. In this reaction system, the SO3(2-) anion acted as a heteroanion template at a lower pH 2.5. 4 was isolated by the combination of cerium(III) centers and SO3(2-) heteroanion template, which is the first lanthanide-containing polyoxotungstates with sulfur heteroatoms, and the 4f metal cerium(III) centers in 4 both have eight-coordinated modes and the SO3(2-) heteroanion templates display μ7 and μ9 coordination modes. At a much lower pH 1.5, the polyanion of 5 was obtained, two triangular-shaped {W36} subunits were bridged by the cerium(III) ions, resulting in the largest lanthanide-containing iso-polyoxotungstates known to date.
