Abstract
Two neutral cyclometalated rhodium and iridium coordination assemblies [(F2ppy)2M(η-Cat)], M = Rh, (2) and M = Ir, (3) (F2ppy: 2,4-difluorophenylpyridine), displaying a masked catecholate (η-Cat = η-O∧O) are described. The catecholate ligand is π-bonded to an organometallic Cp*Ru(II) moiety. The latter brings stability to the whole system in solution and suppresses the formation of the related paramagnetic semiquinone complex. The determination of the molecular structure of the iridium complex [(F2ppy)2Ir(η-Cat)] (3) corroborates the formation of the target compound and reveals the generation of a rare two-dimensional (2D) honeycomb supramolecular architecture in the solid state, in which the Δ-enantiomer self-assembles with the Λ-enantiomer through encoded π-π interactions among individual units. The electrochemistry of complexes 2 and 3 was investigated and showed that reduction occurs at very negative potentials (∼-2.2 V versus saturated calomel electrode (SCE)), while oxidation of the cyclometalated Rh and Ir centers occurs at 0.8 and 0.86 V. In contrast to complexes with 1,2-dioxolene chelates, which are nonemissive, the heterodinuclear diamagnetic complexes 2 and 3 were found to be emissive at room temperature both in solution and in the solid state. Moreover, at 77 K in a solid state, both compounds display opposite emission behavior, for instance, complex 3 displays a blue-shifted emission, while rhodium compound 2 exhibits red-shifted emission to lower energy.

Abstract
![]()
The reaction of the bis(1,2-dithiolene)
complex [Pd(Me2timdt)2] (1; Me2timdt•– = monoreduced 1,3-dimethyl-2,4,5-trithioxoimidazolidine)
with Br2 yielded the complex [Pd(Me2timdt)Br2] (2), which was reacted with Na2mnt
(mnt2– = 1,2-dicyano-1,2-ethylenedithiolate) to
give the
neutral mixed-ligand complex [Pd(Me2timdt)(mnt)] (3). Complex 3 shows an intense solvatochromic
near-infrared (NIR) absorption band falling between 955 nm in DMF
and 1060 nm in CHCl3 (ε = 10700 M–1 cm–1 in CHCl3). DFT calculations were
used to elucidate the electronic structure of complex 3 and to compare it with those of the corresponding homoleptic complexes 1 and [Pd(mnt)2] (4). An in-depth
comparison of calculated and experimental structural and vis–NIR
spectroscopic properties, supported by IEF-PCM TD-DFT and NBO calculations,
clearly points to a description of 3 as a dithione-dithiolato
complex. For the first time, a broken-symmetry (BS) procedure for
the evaluation of the singlet diradical character (DC) of heteroleptic
bis(1,2-dithiolene) complexes has been developed and applied to complex 3. The DC, predominant for 1 (nDC = 55.4%), provides a remarkable contribution
to the electronic structures of the ground states of both 3 and 4, showing a diradicaloid nature (nDC = 24.9% and 27.5%, respectively). The computational
approach developed here clearly shows that a rational design of the
DC of bis(1,2-ditiolene) metal complexes, and hence their linear and
nonlinear optical properties, can be achieved by a proper choice of
the 1,2-dithiolene ligands based on their electronic structure. The reaction of [Pd(Me2timdt)2] (1; Me2timdt•− = monoreduced
1,3-dimethyl-2,4,5-trithioxoimidazolidine) with Br2 yielded
[Pd(Me2timdt)Br2] (2), which was
reacted with Na2mnt (mnt2− = 1,2-dicyano-1,2-ethylenedithiolate)
to give [Pd(Me2timdt)(mnt)] (3), showing an
intense solvatochromic near-infrared (NIR) absorption band. The singlet
diradical character (DC), predominant for 1, provides
a remarkable contribution to the ground states of 3 and 4. A rational design of the DC of bis(1,2-dithiolene) complexes
can be achieved by a proper choice of the 1,2-dithiolene ligands.
