Three bimetallic assemblies, PPh4[Ni(pn)2][M(CN)6]·H2O (M = Fe (1), Cr (2), Co (3); pn = rac-1,2-diaminopropane), have been prepared and structurally and magnetically characterized. Assembly 2 crystallizes in the monoclinic system of the space group P2/c (No. 13) with a = 12.927(2) Å, b = 8.454(2) Å, r = 17.564(2) Å, β= 100.15(1)°, V= 1889.5(6) Å3, and Z = 2, and 3 crystallizes in the same space group with a = 12.971(1) Å, b = 8.437(1) Å, c = 17.118(1) Å, β= 99.84(1)°, V = 1845.7(3) Å3, and Z = 2. The crystal structure analyses of 2 and 3 reveal a one-dimensional zigzag chain structure extending through the M-CN-Ni-NC-M linkages as previously found for 1. Assemblies 1 and 2 show a ferromagnetic intrachain interaction based on the strict orthogonality of the magnetic orbitals between adjacent NiII and MIII (M = Fe, Cr) ions. Assembly 3 is essentially paramagnetic within the chain. All the assemblies show a weak antiferromagnetic interchain interaction and hence no magnetic ordering over the lattice.
