A dimeric complex of [(tren)Ni(mu-Cl)(2)Ni(tren)](ClO4)(2) (1) and a polymeric complex of {[Fe(CN)(6)][Ni(tren)](2) [Ni(tren)(H2O)](2)}Cl-2(ClO4)(2)center dot 4H(2)O (2), are isolated from the reaction of potassium ferricyanide, nickel chloride and tren and their X-ray structures and magnetic properties were characterized. Two [Ni(tren)](2+) units are linked through bis mu-Cl ligands forming dimeric structure of 1. In complex 2, there are two kinds of Ni(II) unit, terminal ([Ni(tren)(H2O)](2+)) and bridged ([Ni(tren)](2+)), and this bridged [Ni(tren)](2+) units are linked with two different Fe(II) ions through mu-NC ligands forming one-dimensional polymeric rectangular chain. 1 shows a weak ferromagnetic coupling between two Ni(II) ions and 2 shows spin crossover in Fe(II) ion.
