Abstract

Three copper(II) complexes, [Cu₂(OAc)₄L ₂]·2CH₃OH (1), [CuBr₂L'2(CH ₃OH)]·CH₃OH (2a), and [CuBr₂L'2(DMSO)] ·0.5CH₃OH(2b) {L = N-(9-anthracenyl)-N'-(3-pyridyl)urea and L' = N-[10-(10-methoxy-anthronyl)]-N'-(3-pyridyl)urea} have been synthesized by the reaction of L with the corresponding copper(II) salts. Complex 1 shows a dinuclear structure with a conventional "paddlewheel" motif, in which four acetate units bridge the two CuII ions. In complexes 2a and 2b, the anthracenyl ligand L has been converted to an anthronyl derivative L', and the central metal ion exhibits a distorted square pyramidal arrangement, with two pyridyl nitrogen atoms and two bromide ions defining the basal plane and the apical position is occupied by a solvent molecule (CH₃OH in 2a and DMSO in 2b).
