- 中文摘要: The reaction of Co(NO3)2·6H2O with two equivalents of PPz (PPz = piperazine hexahydrate) and two equivalents of NH4SCN in CH3OH afforded the complex [Co(NCS)2(PPz)2(CH3OH)2]. The reaction of Ni(NO3)2·6H2O with two equivalents of PPz and four equivalents of NH4SCN in CH3OH afforded the complex [Ni(NCS)4(PPz)2]. Their IR spectra have been recorded and the structures have been determined. Crystal data for 1: space group P, a = 6.7208(6) A, b = 8.4310(8) A, c = 8.5923(8) A, α = 77.881(2)°,β = 76.342(2)°, γ = 83.936(2)°, V = 461.75(1) A3, Z = 1 with final residuals R1 = 0.0650 and wR2 = 0.1725. Crystal data for 2: space group P2(1)/n, a = 7.4209(6) A, b = 11.0231(9) A, c = 12.317(1) A, β = 96.642(9)°, V = 1000.9(2) A3, Z = 2 with final residuals R1 = 0.0378 and wR2 = 0.0809. Important NCS---H-N and O-H---N(PPz) hydrogen-bonding interactions in compound 1 and NCS×××H-N hydrogen-bonding interactions and NCS---SCN interactions in compound 2 play a significant role in aligning the polymer strands in crystalline solids.
