Synthesis and Structures of Cadmium(II) Complexes with (η6‐Benzenecarboxylate)tricarbonylchromium

Abstract

AbstractThe reaction of (benzoic acid)tricarbonylchromium [(η6‐C6H5COOH)Cr(CO)3] with cadmium acetate in methanol or DMF led to the formation of the dinuclear cadmium compounds [Cd2{(η6‐C6H5COO)Cr(CO)3}4(MeOH)4] (1) or [Cd2{(η6‐C6H5COO)Cr(CO)3}4(DMF)4] (2) containing four organometallic ligands with four methanol or DMF molecules coordinated to the cadmium atoms. The reaction of (benzoic acid)tricarbonylchromium [(η6‐C6H5COOH)Cr(CO)3] and cadmium acetate with 1,10‐phenanthroline (1,10‐phen) afforded the dinuclear cadmium complex [Cd2{(η6‐C6H5COO)Cr(CO)3}4(1,10‐phen)2] (3) with two 1,10‐phenanthroline and four organometallic ligands. The reaction of (benzoic acid)tricarbonylchromium [(η6‐C6H5COOH)Cr(CO)3] with cadmium acetate in the presence of 4,4′‐bipyridine (4,4′‐bipy) led to the one‐dimensional coordination polymer [Cd2{(η6‐C6H5COO)Cr(CO)3}4(4,4′‐bipy)2·3DMF]n (4) containing a dinuclear cadmium complex as a repeating unit. The solid‐state structures of all the compounds were determined by single‐crystal X‐ray diffraction.
