摘要

Black crystals Of W2Cl7(CCl) were obtained from the reaction Of WCl6 and As in CCl4 at 250 degreesC under solvothermal conditions. The crystal structure (orthorhombic, space group Phca, a = 1196(1), b = 1215.6(7), c = 1584(l) pin, Z = 8) is built of infinite zig-zag chains of dinuclear complexes connected via bridging Cl atoms. The individual complexes are face-sharing double octahedra concatenated via bridging Cl ligands. Each W atom is in a distorted octahedral coordination environment of five Cl atoms an the carbon atom of the mu(2) bridging chloromethylidyne ligand leading to the formula [(Cl2W(mu-CCl)(mu(2)-Cl)(2) WCl2)(mu-Cl)](n). The short W-W distance of 256 pin indicates a multiple W-W bond, the W-C bonds of 195 pin are in the typical range for mu(2)-alkylidyne ligands, the C-Cl bond of 167 pin is consistent with a sp(1) hybridisation on the carbon atom.
