Abstract

[Methylamino-(N,N'-1,3-propyl-disalicylaldiminato)- -Ni(II)-bis-(N-methylsalicylaldiminato)-NI(II)] was synthesized from the condensation of N,N'-1,3-propyl-disalicylaldimine, salicylaldehyde, methylaminohydrochloride, NaOH and Ni(CH3COO)(2) . H2O, and its crystal structure determined. [C34H37N5O4Ni2], orthorhombic. space group Pbca, a = 12.330(1), b = 24.967(2), c = 20.616(2)Angstrom, Z = 8. The dinuclear complex contains two octahedrally coordinated nickel atoms which are linked via three oxygen atoms with an average [Ni-O-Ni] angle of 87.2(1)degrees and a Ni ... Ni distance of 2.884(1)Angstrom. The coordination is completed by three nitrogen atoms. The nickel(II) centers are ferromagnetically coupled (J = 11.5 cm(-1)) as derived from temperature-dependent magnetic susceptibility measurements in the range 5 - 280 K.
