The structure consists of a trinuclear [Cu(bappz)(mu-NC)Ni(CN)2(mu-CN)Cu(bappz)]2+ cation and two perchlorate anions. The bridging [Ni(CN)4]2- anion is coordinated by two [Cu(bappz)]2+ cations through two cyano groups, providing a novel trinuclear structure with the Cu-(NC)-Ni-(CN)-Cu linkage. The nickel(II) ion is four-coordinated by carbon atoms from four cyano groups (two of them, in trans position, form a bridge) in a square planar arrangement, whereas both the copper(II) ions are five-coordinated by four bappz nitrogens and one cyanide nitrogen in a distorted square-pyramidal geometry. The temperature dependence of magnetic susceptibility was measured for this compound over the range of 2-300 K. The magnetic investigation showed the presence of a very weak antiferromagnetic interaction (superexchange interaction parameter J=-0.54 cm-1) between the copper atoms through the diamagnetic [Ni(CN)4]2- ion.
