Abstract: A novel polymer of a binuclear nickel(II) complex of [Ni2L(?-H2N-(CH2)3-NH 2)2�(H2O)2] n(ClO4)n�(H2O)n (where L = [2 + 2] condensation of 2,6-diformyl-4-methylphenol with 1,3-diaminopropane) has been synthesized and characterized. The crystal structure of the compound has been solved. The compound crystallizes in the monoclinic system, space group P21/a. with formula weight = 901.004, a = 13.918(2) �, b = 18.111(3) �, c = 16.079(2) �, ?= 103.46(3)�, and Z = 4. The interesting feature of this compound is the bridging behavior of 1,3-diaminopropane in an end-to-end fashion. Nickel atoms are placed in a distorted octahedral environment. The magnetic properties of the compound have been studied by means of susceptibility measurement vs temperature, which reveals a moderately strong intramolecular antiferromagnetic coupling (J) of -30 � 4 cm-1 and a weak intermolecular ferromagnetic coupling (zJ') of 2 �1 cm-1.
