摘要:
AbstractA template synthesis procedure yielded [Ni(HL1)NH3]I, where HL1is the monoanion of the terdentate ONN benzoylacetone S‐methylisothiosemicarbazone ligand. The reaction of this complex with an excess of NH4NCS, pyridine, or hydrazine resulted in the complexes [Ni(HL1)(NH3)NCS] and [Ni(L1)A] (A = Py, N2H4). The monoanionic form of the ligand is obtained by deprotonation of the enolic form of the benzoylacetone moiety, whereas the dianion is formed by additional deprotonation of the terminal NH2group. Finally, the reaction of [Ni(HL1)NH3]I with salicyladehyde produced the NiL2complex in which L2stands for the dianion of the ONNO ligand N(1)‐2‐butylidene‐4‐oxo‐4‐phenyl‐N(4)‐salicylidene‐S‐methylisothiosemicarbazide. All complexes are diamagnetic and have a square‐planar configuration, except for [Ni(HL1)(NH3)NCS], for which te data of i.r. spectra suggest a square‐pyramidal structure. The electronic absorption spectra of the ethanolic solutions of all complexes are characteristic of typical square‐planar
