摘要：
Crystals of the 2CuCl . HC=CCH2OH complex were prepared by the direct reaction of CuCl with propargyl alcohol in a hydrochloric solution and studied by X-ray diffraction analysis [a DARCh automated diffractometer, lambda MoKalpha, theta/2 theta scan mode, 1965 independent reflections with F greater than or equal to 4 sigma(F), R = 5.0%]. The crystals are monoclinic, a = 20.059(5), b = 15.187(5), c = 6.196(2) Angstrom, gamma = 101.81(2)degrees, space group P2(1)/a, Z = 12. The C=C bond of the HC=CCH2OH molecule functions as a bridging pi-ligand in the structure and is bound simultaneously to two copper(I) atoms. The =C-H ... Cl hydrogen bonds [H ... Cl 2.6-2.9(1) Angstrom] and contacts of the R-OH ... O(H)R type [H ... O 1.8, 2.1(1) Angstrom] stabilize the structure.
