Abstract

Treatment of (η6-benzoic acid)tricarbonylchromium withlead(II) acetate in the presence of trans-1,2-bis(4-pyridyl)ethene (bpe) afforded the one-dimensional coordination polymer [Pb{(η6-C6H5COO)Cr(CO)3}2bpe]n (1). In contrast, the reaction of (η6-benzoic acid)tricarbonylchromium with lead(II) acetate in the presence of 1,10-phenanthroline (1,10-phen) or 2,2′-bipyridine (2,2′-bipy) gave the lead(II) compounds [Pb{(η6-C6H5COO)Cr(CO)3}2(1,10-phen)] (2) and [Pb{(η6-C6H5COO)Cr(CO)3}2(2,2′-bipy)] (3). The solid-state structures of all compounds were determined by single-crystal X-ray diffraction.
