Abstract

Reaction of K3[Cr(CN)6] with [CuL1](ClO4)2 (L1 = 3,10-dipropyl-1,3,5,8,10,12-hexaazacyclotetradecane) leads to a novel three-dimensional (3-D) cyano-bridged bimetallic assembly [CuL1]2[Cr(CN)6]ClO4·0.5H2O (1), in which each hexacyanochromate(III) ion connects four copper(II) ions using four co-planar CN− groups, which coordinate axially to the copper ion in a trans fashion forming trans-CuL1(N[triple bond, length as m-dash]C)2 moieties. Magnetic studies reveal that the complex displays a ferromagnetic interaction between the Cu(II) (S = 1/2) and Cr(III) (S = 3/2) ions through cyano bridges.
