Synthesis, structures, and properties of seven transition metal coordination polymers based on a long semirigid dicarboxylic acid ligand

Seven coordination polymers based on a long dicarboxylic acid ligand present diverse structures. The photoluminescence and magnetic properties of some compounds were explored.

Syntheses, characterization, and properties of five coordination compounds based on the ligand tetrakis(4-pyridyloxymethylene)methane

Based on tetrakis(4-pyridyloxymethylene)methane (TPOM) and different carboxylates, five new MOFs with structures of high dimension and mutual interpenetration have been successfully synthesized.

Biphase synthesis of a one-dimensional coordination polymer based on a dinuclear Cd(II) secondary building unit and a novel semi-rigid dicarboxylate

A one-dimensional coordination polymer, namely catena-poly[[aquapyridinecadmium(II)]-μ(3)-{4,4'-[(2,4,6-trimethyl-1,3-phenylene)bis(methylene)]dibenzoato}], [Cd(C(25)H(22)O(4))(C(5)H(5)N)(H(2)O)](n), has been synthesized by a biphasic solvothermal reaction. The Cd(II) cation is located in a CdO(5)N six-coordinated environment. The trans 4,4'-[(2,4,6-trimethyl-1,3-phenylene)bis(methylene)]dibenzoate ligand connects the Cd(II) cations to form a one-dimensional ribbon incorporating centrosymmetric [Cd(2)(COO)(2)] secondary building units. Inter-ribbon O-H...O hydrogen bonds extend the one-dimensional ribbons into a two-dimensional sheet. No π-π interactions are observed. Comparing products synthesized using a different method, it was found that biphasic solvothermal conditions play a crucial role in obtaining large well-shaped single crystals; only intractable precipitates were obtained by the traditional single-phase solvothermal method.

Poly[bis(2,2'-bipyridine-κ(2)N,N')bis(μ(6)-2,4,6-trimethylbenzene-1,3,5-tricarboxylato)tricadmium(II)], a two-dimensional 'Kagomé dual' (kgd) sheet structure

The title metal-organic framework, [Cd(3)(C(12)H(9)O(6))(2)(C(10)H(8)N(2))(2)](n), has been synthesized by a solvothermal reaction. The Cd(II) ions are located in CdO(4)N(2) and CdO(6) six-coordinated environments, with the latter Cd(II) ion lying on an inversion centre. The 2,4,6-trimethylbenzene-1,3,5-tricarboxylate ligand (TMBTC) connects the Cd(II) ions to form a two-dimensional sheet incorporating hourglass-like [Cd(3)(COO)(6)] secondary building units (SBUs). Topologically, taking the TMBTC ligand and the [Cd(3)(COO)(6)] SBU as 3- and 6-connected nodes, respectively, the overall two-dimensional sheet can be simplified to a rare (3,6)-connected 2-nodal kgd (Kagomé dual) net with a short Schläfli vertex notation of {4(3)}(2){4(6).6(6).8(3)}, which further stacks into a three-dimensional supramolecular framework through π-π stacking interactions.
