摘要：

The preparation of sodium dihydrobis(1,2,3-benzotriazolyl)borate was realised by refluxing one mole of sodium borohydride with two moles of 1,2,3-benzotriazole in toluene over a period of 12 h. Its complexes with MCl2 center dot py(2)2 [where M = Mn(II), Fe(II), Co(II), Ni(II), Cu(II) and py = pyridine] were characterized by elemental analysis as well as magnetic, spectroscopic and conductivity measurements. On the basis of these studies, it is proposed that the geometry of all the complexes is octahedral. The ligand field parameters 10 Dq, B and P show extensive overlap between the M-L orbital. The molar conductance of 10(-3) M Solutions of the Complexes in DMSO suggest them to be non-ionic in nature.
