Abstract

Reaction of [Ni(rac-CTH)(ClO4)2] (rac-CTH = rac-5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane) with NaN3 and Cu(NO3)2·3H2O produces the binuclear complex [Ni(rac-CTH)(µ1,1-N3)2Cu(N3)2] 1, which represents the first example of an end-on bridged bimetallic complex; 1 exhibits intramolecular ferromagnetic exchange coupling and thermochromism, this latter being a consequence of the intermolecular interaction at low temperature.
