title: Di-μ(2)-cyanido-dicyanidobis{2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato}(1,4,8,11-tetra-azacyclo-tetra-deca-ne)dichromium(III)nickel(II) methanol disolvate.
abstract: In the title compound, [Cr(2)Ni(C(16)H(14)N(2)O(2))(2)(CN)(4)(C(10)H(24)N(4))]·2CH(3)OH, each [Cr(salen)(CN)(2)] unit {salen is 2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]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.
