A new Schiff base ligand of 1-(2, 6-dichlorobenzylidene)-4-phenylthiosemicarbazide(C14H11Cl2N3S) has been synthesized, which crystallizes in monoclinic, space group C2/c with a = 18.551(7) Å, b = 6.963(3) Å, c = 23.185(9) Å and β = 93.122(6)º. The reaction of this ligand with NiAc2·4H2O gives two different Ni(II) complexes, one is general traditional mononuclear and another is unexpected trinuclear, where another quadridentate ligand of 1-(amino-N-phenylmethanethio)-4-phenyl-thiosemicarbazide(C14H14N4S2) is found. The mononuclear complex (C32H26Cl4N8NiS2) crystallizes in triclinic, space group P−1 with a = 11.071(2) Å, b = 11.157(2) Å, c = 15.302(3) Å, α = 76.214(2)º, β = 87.902(2)º and γ = 79.586(3)º. The trinuclear complex (C60H50Cl4N16Ni3S6) crystallizes in orthorhombic, space group Pbcn with a = 19.673(3) Å, b = 16.094(3) Å and c = 20.465(4) Å. In above three compounds, there are some hydrogen bonds which help to construct the three dimensional net works and stabilize the molecular structures. Two Ni(II) complexes with mononuclear and trinuclear conformations, respectively, have been obtained by one reaction of NiAc2·4H2O with a new Schiff Base ligand of 1-(2, 6-dichlorobenzylidene)-4-phenylthiosemicarbazide.
合成了一种新的舒弗碱配体1-(2, 6-二氯苄亚基)-4-苯基噻唑氨基脲(C14H11Cl2N3S),其结晶为单斜晶系,空间群为C2/c,参数 a = 18.551(7) Å, b = 6.963(3) Å, c = 23.185(9) Å,β = 93.122(6)º。该配体与NiAc2·4H2O反应形成两种不同的Ni(II)络合物,其中一种是常规的单核络合物,而另一种是意想不到的三核络合物,后者中发现了另一种四齿配体1-(氨基-N-苯基甲硫)-4-苯基噻唑氨基脲(C14H14N4S2)。单核络合物(C32H26Cl4N8NiS2)结晶为三斜晶系,空间群为P−1,参数 a = 11.071(2) Å, b = 11.157(2) Å, c = 15.302(3) Å,α = 76.214(2)º, β = 87.902(2)º, γ = 79.586(3)º。三核络合物(C60H50Cl4N16Ni3S6)结晶为正交晶系,空间群为Pbcn,参数 a = 19.673(3) Å, b = 16.094(3) Å, c = 20.465(4) Å。在上述三种化合物中,存在一些氢键,这些氢键有助于构建三维网络并稳定分子结构。通过一反应,将NiAc2·4H2O与新的舒弗碱配体1-(2, 6-二氯苄亚基)-4-苯基噻唑氨基脲结合,分别获得了单核和三核构型的两种Ni(II)络合物。
