Syntheses, spectral and crystallographic studies of novel monometallic Co(II) and Zn(II) complexes with phenyl-(5-pyridin-4-yl[1,3,4]thiadiazol-2-yl)-amine
摘要:
Two novel monometallic complexes [Co(ppt)(SO4)(H2O)(4)]center dot H2O (1) and [Zn(ppt)(2)(CH3COO)(2)(H2O)(2)]center dot(2) of ppt = phenyl-(5-pyridin-4-yl[1,3,4]thiadiazol-2-yl)-amine have been synthesized and their structures investigated by elemental analyses, IR. UV-Vis., magnetic susceptibility and single crystal X-ray. The geometry of both complexes are distorted octahedral. The pi-pi and C-H center dot center dot center dot pi interactions play important role along with hydrogen bonding to form host-guest cavity. The hydrogen-bonding interactions between adjacent layers extend these structures to overall 3D supramolecular architectures. (C) 2010 Elsevier B.V. All rights reserved.
