Tris­(ethyl­enedi­amine‐κ2N,N′)­cadmium(II) bis­(1,2‐dicyanoethylenedithiolato‐κ2S,S′)­cuprate(II)

In the title complex, [Cd(C2H8N2)3][Cu(C4N2S2)2], the CdII atom has a distorted octahedral geometry. The CuII atom is in a distorted square-planar geometry. Both ions lie on twofold rotation axes. They are not connected covalently.

Tetrakis(μ-2-bromo­benzoato-κ2O,O′)­bis­[(N,N′-di­methyl­form­amide)copper(II)], a new binuclear complex containing a metal–metal bond

The dimeric neutral title complex, [Cu-2(C7H4BrO2)(4)(C3H7NO)(2)], is centrosymmetric and contains a Cu-Cu bond [2.636 (3) Angstrom].

Tris­(ethyl­enedi­amine-κ2N,N′)­zinc(II) bis(1,2-di­cyano­ethyl­enedi­thiol­ato-κ2S,S′)­nickelate(II)

The title complex, [Zn(C2H8N2)3][Cu(C4N2S2)2], exists as discrete ions. The cation lies on a twofold rotation axis and the anion lies on an inversion centre. The [Zn(C2H8N2)3]2+ cation exhibits a distorted octahedral geometry. In the [Cu(C4N2S2)2]2− anion, the CuII atom is in a slightly distorted square-planar environment. The crystal packing is stabilized by hydrogen bonds of the types N—H⋯N and N—H⋯S.
