Single-crystal X-ray diffraction analysis reveals their different structure ranging from a cyanide-bridged cationic polymeric single chain for 1, a two-dimensional network for 2 and 3, and a three-dimensional network for 4 and 5. In addition, a systematic investigation over the magnetic properties of 13 indicates the ferromagnetic magnetic coupling between neighboring Fe­(III)/Cr­(III) and Ni­(II) ions through the bridging cyanide group. For complex 1, the magnetic susceptibility has been simulated by the Seiden model using the Hamiltonian H = –Ji=0NSiSi+1, leading to the magnetic coupling constant of J = 3.67 cm–1. The two-dimensional magnetic complexes exhibit three-dimensional magnetic ordering behavior with a magnetic phase transition temperature of TC = 4.0 K for 2 and TN = 6.0 K for 3, respectively. %I ACS Publications
