title: Cyano-bridged extended heteronuclear supramolecular architectures with hexacyanocobalt(III) as building blocks.
abstract: The cyano-bridged heteronuclear coordination polymer poly[tris[(5,12-dimethyl-7,14-diphenyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene)copper(II)]-hexa-mu-cyano-bis[tricyanocobalt(III)] dimethylformamide solvate trihydrate], {[Cu3Co2(CN)12(C24H32N4)3].C3H7NO.3H2O}n, was synthesized by the assembly reaction of [CuL]2+ (L is 5,12-dimethyl-7,14-diphenyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene) and [Co(CN)6]3- in a dimethylformamide-water solution. The structure consists of neutral cyano-bridged Cu3Co2 units with the unique Co atom in a general position and all three Cu atoms on independent inversion centres. Each [Co(CN)6]3- ion connects three CuII ions via three cyano groups to form a novel cyano-bridged two-dimensional stair-shaped-layer structure. The water and dimethylformamide molecules are situated in the inter-fragment spaces.
