“…The calculated interatomic distances in molecule 1 and the cation [Pt 2 (OCOMe) 4 (H 2 O) 2 ] 2+ [8] adequately agree with the experimental data (Table 1), taking into account common overestimation of the M···M distances in calculations using the SDD basis [28]. Table 1 (two first lines) and Figs.…”

“…The antibonding σ*-MO of molecular complex 1 is also not occupied, resulting in a short Pt-Pt distance and σ-bonding, analogously to other binuclear transition metal complexes containing 14 valent electrons at the "metallic" MOs [27,28]. However, this σ*-MO becomes a (LUMO+1) because of a rather antibonding effect of the axial ligands (cf.…”

“…In contrast to the computational results on B26 and B39 described above, DFT calculations on models for B6−B8 along with the hypothetical Fe analog were performed, and the authors of this study concluded that these compounds do not contain heterometallic metal−metal bonds. 126 Their conclusion was based on inspection of only the frontier orbitals and the lack of a Pd−M natural orbital from NBO analysis.…”

Significant progress has been made in the past 10–15 years on the design, synthesis, and properties of multimetallic coordination complexes with heterometallic metal–metal bonds that are paramagnetic. Several general classes have been explored including heterobimetallic compounds, heterotrimetallic compounds of either linear or triangular geometry, discrete molecular compounds containing a linear array of more than three metal atoms, and coordination polymers with a heterometallic metal–metal bonded backbone. We focus in this Review on the synthetic methods employed to access these compounds, their structural features, magnetic properties, and electronic structure. Regarding the metal–metal bond distances, we make use of the formal shortness ratio (FSR) for comparison of bond distances between a broad range of metal atoms of different sizes. The magnetic properties of these compounds can be described using an extension of the Goodenough–Kanamori rules to cases where two magnetic ions interact via a third metal atom. In describing the electronic structure, we focus on the ability (or not) of electrons to be delocalized across heterometallic bonds, allowing for rationalizations and predictions of single-molecule conductance measurements in paramagnetic heterometallic molecular wires.
