Abstract The influence of the substituents (R) at the N1 nitrogen of heterocyclic thiosemicarbazones (C4H3X)–C(H) N3–N2H–C1( S)N1HR; X = O, Hftsc; S, Httsc} on the geometry of nickel(II) complexes was investigated. Furan-2-carbaldehyde thiosemicarbazones have formed both trans [Ni(ftsc-N-R)2] (R = Me, 1; Et, 2), and cis (R = Ph, 3), square planar complexes unlike thiophene-2-carbaldehyde thiosemicarbazones
摘要 杂环缩氨基硫脲的 N1 氮上的取代基 (R) 的影响 (C4H3X)–C(H) N3–N2H–C1(S)N1HR; X = O, Hftsc; S, Httsc} 对镍 (II) 配合物的几何形状进行了研究。呋喃-2-甲醛缩氨基硫脲形成了反式 [Ni(ftsc-NR)2] (R = Me, 1; Et, 2) 和顺式 (R = Ph, 3) 方形平面复合物,与噻吩-2-甲醛不同缩氨基硫脲仅产生反式方形平面复合物 [Ni(ttsc-NR)2] (R = Me, 4; Et, 5; Ph, 6)。
