Coordinating and hydrogen bonding ability of a bifunctional 2D paddle-wheel copper(II) coordination polymer
abstract A new copper(II) complex of formula {[Cu 2 (H 2 btc) 2 (dmf) 2 ] 4dmf} n (1)[H 4 btc = 1,2,4,5-benzenetetracarb-oxylic acid, dmf = dimethylformamide] has been synthesised and its structure determined by X-raydiffraction. The structure displays a new square grid of ‘‘paddle-wheel’’ tetracarboxylate-bridgeddicopper(II) units with an intradimer copper–copper separation of 2.619(2) A. The dmf molecules areretained through weak axial coordinative bonds and hydrogen bonding interactions with the carboxylicgroups of the porous neutral network of 4 4 net topology. The magnetic behaviour of 1 corresponds to astrong antiferromagnetic coupling within each dicopper(II) unit (J = 343 cm 1 with …
