Mononuclear complexes of 4-amino-3,5-bis(pyridin-2-yl)-1,2,4-triazole containing tripodal tris(3-aminopropyl)amine: crystal structure of [Ni(trpn)(abpt)](ClO4)(2)

摘要

Complexes of the type [M(trpn)(abpt)](ClO4)(2) (1-6) [M = Mn, Fe, Co, Ni, Cu, Zn, trpn = tris (3-aminopropyl)amine, abpt = 4-amino-3,5-bis (pyridin-2-yl)-1,2,4-triazole] have been synthesized. The mode of bonding and overall geometry of these complexes have been deduced by elemental analyses data, molar conductance values, spectral studies obtained from FT-IR, H-1 NMR and electronic spectral analyses and magnetic susceptibility measurements. The structure of complex 4 has been determined by single Xray crystallography. On the basis of the above physicochemical studies and the single X-ray crystallographic data recorded on complex 4, an octahedral geometry has been suggested for all the complexes.
