Hz. Kou et al., SYNTHESIS AND MAGNETISM OF BINUCLEAR GD(III), DY(III) AND ND(III) COMPLEXES WITH BROMANILATE DIANION AS BRIDGING LIGAND, Synthesis and reactivity in inorganic and metal-organic chemistry, 28(2), 1998, pp. 303-309
Three new binuclear lanthanide(III) complexes, Ln(2)(phen)(4)(BA)(ClO4
)(4) . nH(2)O (Ln = Nd and Dy, n = 3; Ln = Gd, n = 1; phen = 1,10-phen
anthroline; BA(2-) = bromanilate dianion), have been synthesized and c
haracterized. The variable-temperature magnetic susceptibilities of Gd
-2(phen)(4)(BA)(ClO4)(4) . H2O were measured over the temperature rang
e 4-300 K. The observed susceptibility data were best-fit to those fro
m the theoretical magnetic equation by a least-squares method, giving
the following parameters: J = -0.10 cm(-1), g = 1.95, R = 7.9x10(-3).
