Di-μ₂-cyanido-dicyanidobis{2,2′-[ethane-1, 2-diylbis(nitrilomethylidyne)]diphenolato}(1,4,8,11-tetraazacyclotetradecane) dichromium(III)nickel(II) methanol disolvate

In the title compound, [Cr₂Ni(C₁₆H₁₄N ₂O₂)₂(CN)₄(C₁₀H ₂₄N₄)]·2CH₃OH, each [Cr(salen)(CN) ₂] unit {salen is 2,2′-[ethane-1,2-diylbis(nitrilomethylidyne)] diphenolate} acts as a monodentate ligand through one of its two cyanide groups N bound to a central [Ni(cyclam)]²⁺ core (cyclam is 1,4,8,11-tetra-azacyclo-tetra-deca-ne). Each Cr^III ion is coordinated by two N and two O atoms from a salen ligand situated in the equatorial plane with two trans cyanide C atoms, yielding a distorted octa-hedral coordination geometry. The Ni^II atom lies on an inversion center and is octa-hedrally coordinated by a cyclam ligand lying in the equatorial plane and by two cyanide N atoms. The asymmetric unit contains one half of the complex mol-ecule and a methanol solvent mol-ecule. In the crystal structure, the complex mol-ecule is linked to the methanol solvent mol-ecules via O - H⋯O and N - H⋯O hydrogen bonds. Individual complex mol-ecules are linked by C - H⋯N hydrogen bonds, forming chains along b.
