摘要：

Hydrothermal reaction of copper(II) bromide with either bis(4-pyridylmethyl)piperazine (bpmp) or bis(4-pyridylformyl)piperazine (bpfp) afforded layered coordination polymer solids. The racemic S,S and R, R stereochemistry dped ligands in [Cu2Br2(dped)](n) (1, dped = 1,2-di(4-pyridyl)ethanediol) were formed by the in situ transformation of bpmp via putative 4-pyridylmethanol intermediates, along with concomitant reduction to monovalent copper. The structure of 1 contains [Cu2Br2](n) chains comprising edge-shared [Cu3Br3] boat-conformation six-membered rings, linked into layer motifs by dped tethers with alternating stereochemistry. Lack of benzylic hydrogen atoms in bpfp causes that ligand to stay intact under the reaction conditions, generating the 2-D layered divalent copper phase [CuBr2(bpfp)](n) (2). (C) 2011 Elsevier B. V.
