Abstract

[Fe(L)Cl](2) (L = N-(4-methylphenyl)-3-methoxy-salicylaldimimine) was synthesized and its crystal structure determined. [C30H26Cl2Fe2N2O6], triclinic, space group P 1, a 9.278(2), b = 9.4050(10), c = 10.489(2) Angstrom, alpha = 64.43(2), beta = 74.540(10), gamma = 62.40(2)degrees, V = 729.1(2) Angstrom(3), Z = 1. Two identical [Fe(L)Cl] fragments, related by an inversion center, are connected by two bridging 0 atoms to form a binuclear unit. The iron(III) centers are separated by 3.196(2) Angstrom and weakly antiferromagnetically coupled (J = -10.1(1) cm(-1)), as derived from temperature-dependent magnetic susceptibility measurements in the range 5.1-283.5 K.
