Three copper(II) complexes, [Cu 2 (OAc) 4 L 2 ] · 2CH 3 OH ( 1 ), [CuBr 2 L′ 2 (CH 3 OH)] · CH 3 OH ( 2a ), and [CuBr 2 L′ 2 (DMSO)] · 0.5CH 3 OH ( 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 Cu II 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 (CH 3 OH in 2a and DMSO in 2b ).
