摘要

Treatment of [Re-2(CO)(8)(MeCN)(2)] with excess 1-vinylimidazole in refluxing benzene gives three new compounds [Re-2(CO)(9){eta(1)-NC3H3N(CH=CH2)}] (1), [Re-2 (CO)(8){eta(1)-NC3H3N(CH=CH2)}(2)] (2) and [ReCl2(CO)(2) {eta(1)-NC3H3N(CH=CH2)}(2)] (3) in 11, 32 and 2% yields, respectively. The solid-state structures of complexes 2 and 3 have been determined by single crystal X-ray diffraction studies. Compound 2 crystallizes in the monoclinic space group C2/c, with lattice parameters a = 13.8378(5) angstrom, b = 11.8909(5) angstrom, c = 14.4591(6) angstrom, beta = 116.6470(10)degrees, Z = 4 and V = 2131.99(15) angstrom(3). Compound 3 crystallizes in the monoclinic space group C-2/c, with lattice parameters a = 10.1028(3) angstrom, b = 13.5640(5) angstrom, c = 12.5398(4) angstrom, beta = 109.637(2)degrees, Z = 4 and V = 1618.4(9) angstrom(3). The disubstituted dinuclear compound 2 contains two 1-vinylimidazole ligands coordinated through the imino nitrogen atoms at the equatorial sites, whereas the mononuclear compound 3 contains two carbonyl ligands, two N coordinated g eta(1)-1-vinylimidazole ligands and two terminal Cl ligands.
