A new tetranuclear cyanide-bridged complex [PPh4]2[NiⅡ(CN)4CuⅠ(PPh3)2]2·2CH3OH ([PPh4]+ = tetraphenylphosphine cation, PPh3 = triphenylphosphine) 1 has been synthesized and characterized by IR spectroscopy, elemental analysis, electronic absorption spectra and single-crystal X-ray diffraction. This complex crystallizes in triclinic, space group Pí with a = 10.910(5), b = 15.777(7), c = 18.275(8), α = 68.752(12), β = 79.776(13), γ = 81.400(14)°, NiCuC65H50N4OP3, Mr = 1122.25, V = 2873(2)3 , Z = 2, Dc = 1.293 g/cm3, F(000) = 1156, μ = 0.826 mm-1, the final R = 0.0755 and wR = 0.2155 for 7324 observed reflections (I > 2σ(I)). The title compound exhibits a discrete square tetranuclear structure and a cubic order NLO property. 相似文献

Under hydrothermal conditions, two new ribbon-like structures, [Cu(C14H9O4)-analysis revealed that these structures were constructed by mixed ligands. The coordination polymer forms the basic architecture while the weak interactions extend the framework into a secondary structure. The whole structures of them are governed by collaboration of the strong and weak interactions. Compound 1 crystallizes in monoclinic, space group C2/c with a = 17.0485(3), b =1 1.0558(3), c = 22.7623(4) A, β = 102.465(1)°, V = 4189.2(2) A3, Z = 4, Mr = 915.44, Dc = 1.451g/mL, F(000) = 1900 andμ(MoKα) = 0.587 cm-1. The final R and wR are 0.0030 and 0.1022,respectively for 3037 observed reflections with I > 2σ(I). Compound 2 crystallizes in monoclinic,space group P21/c with a = 11.5963(4), b = 11.7004(5), c = 17.1254(5) A,β = 95.620(1)°, V =2312.4(1) A3, Z = 4, Mr = 556.35, Dc = 1.598 g/mL, F(000) = 1132 andμ(MoKα) = 0.912 cm-1The final R and wR are 0.0431 and 0.1050, respectively for 2629 observed reflections with I > 2σ(I). 相似文献
