Copper(II) complexes of the type Cu[Ag(SCN) 2 ] 2 ÁL (where L is acetophenone benzoyl hydrazone, acetophenone isonicotinoyl hydrazone, acetophenone salicyloyl hydrazone, acetophenone anthraniloyl hydrazone, p-hydroxyl acetophenone benzoylhydrazone, p-hydroxyl acetophenone isonicotinoyl hydrazone, p-hydroxyl acetophenone salicyloyl hydrazone, or p-hydroxyl acetophenone anthraniloyl hydrazone) were synthesized and characterized. All the complexes were polymeric and insoluble in common organic solvent and were nonelectrolytes. The ligands were coordinated through >C¼ ¼O and >C¼ ¼NÀ À groups. All the SCN groups present in the complexes acted as bridges between two metal centers, resulting in a polymeric structure of the Lewis acid Cu[Ag(SCN) 2 ] 2 as well as its complexes. Electronic and electron spin resonance spectra suggested a square planar geometry for the Lewis acid and an elongated tetragonally distorted octahedral geometry for all the complexes. The powder X-ray diffraction parameters for acetophenone salicyloyl hydrazone and p-hydroxyl acetophenone anthraniloyl hydrazone complexes corresponded to orthorhombic and tetragonal crystal lattices, respectively. The complexes showed a fair degree of antifungal activity against Rizoctonia sp., Aspergillus sp., and Stemphylium sp. and moderate antibacterial activity against Clostridium sp. (Gram-positive) and Pseudomonas sp. (Gram-negative). The complexes were more active than the parent ligands.

“…Dinuclear metal complexes are often postulated as simple models with which to study the interactions of molecules with metal surfaces [4,5]. For the bridged bis(cyclopentadienyl) metal carbonyl dimers, the nature of a bridge has important effect on the metal-metal bond and its reactivity [6][7][8][9][10][11][12][13][14][15][16].…”

Heterodinuclear transition‐metal complexes, that is coordination compounds comprising two different transition‐metal atoms, witness growing interest. This development is driven by the incentive to find complexes, which outperform their mononuclear competitors in reactivity and selectivity. It is particularly the close proximity of the two transition‐metal atoms, which promises to promote these favorable interactions denoted as “cooperative”. Therefore, mainly dinuclear complexes with direct metal–metal bonds are discussed in this article. Since the very first report of a heterodinuclear transition‐metal complex in 1960, a repertoire of methodologies for the targeted synthesis has been established. Besides the description of this progress, the focus of the present article is on the discussion of appropriate characterization methods. Typical questions concern the nature of the metal–metal bond as well as the elucidation of mechanistic details of reactions involving the polar metal–metal bonds present in heterodinuclear complexes. Several applications are detailed, in which heterodinuclear complexes either surpass the limitations of mononuclear complexes or even exhibit so far unknown reactivity. So‐called “early–late” complexes represent the most dominant branch in this context, while also “late–late” complexes show fruitful reactivity. Herein, the focus is on transition‐metal‐containing complexes, thus ignoring main‐group elements completely.
