摘要: Abstract The structure of the diphenylacetylene complex Ni(C6H5CCC6H5)[(CH3)3CNC]2 has been determined from X-ray data collected by counter methods. compound crystallizes in space group C2h5−P21/a with eight molecules cell dimensions a = 29.580(12), b 10.803(5), c 15.136(5) A, β 107.85(5)°. structures two independent asymmetric unit are similar overall detail. In each, Ni atom trigonal coordination if is regarded as monodentate ligand, and inner sphere essentially planar. carbon atoms equidistant metal each molecules. average CC distance 1.285(20) A intermediate between normal CC CC bond lengths. phenyl rings coordinated bent away about 31° axis.
