摘要:
The crystalline complex ImH[CuCl2(HOCH2C CCH2OH)] has been synthesized by the direct interaction of 2-butyne-1,4-diol with CuCl in concentrated aqueous solution of (ImH)Cl (ImH(+) is imidazolium cation) and studied by X-ray crystallography. The crystals are triclinic, space group P1, a = 7.08(2) angstrom, b = 7.49(1) degrees, c = 10.962(8) angstrom, alpha = 101.76(8)degrees, beta = 95.85(8)degrees, gamma = 99.57(8)degrees, Z = 2. The structure consists of stacks of discrete anions [CuCl2(HOCH2C CCH2OH)](-) arranged along the [100] axis and [ImH](+) cations occupying the free space. The environment of pi-coordinated Cu(I) atoms is trigonal and consists of two chlorine atoms and the C C bond of 2-butyne-1,4-diol molecule. The alcohol groups do not participate in the coordination, but they form strong hydrogen bonds N-H center dot center dot center dot O (H center dot center dot center dot O, 1.76(6) angstrom) and O-H center dot center dot center dot Cl(H center dot center dot center dot Cl, 2.29(5) angstrom).
