Two new metal-organic frameworks [Co(pydc)(H(2)O)(2)](n) (1) and [Co(pydc)(H(2)O)(4)](n)(H(2)O)(n) (2), (pydc = 3,5-pyridinedicarboxylate) have been synthesized by a diffusion method and characterized by single-crystal X-ray diffraction. The structure of 1 reveals an infinite 2D layer with honeycomb-like cavities in which each pydc ligand bridges three Co(II) ions. The adjacent 2D layers are or...

This study reports chromotropism of two newly synthesized copper(II) complexes formula [CuLCl2] and [CuLBr2]•MeOH where L = N-(2-pyridylmethyl)-1-hydroxypropylamine. The structure the was investigated by infrared spectroscopy, electronic absorption elemental analysis, molar conductance measurements, thermal analysis. Single Crystal X-ray determination reveals both to adopt a distorted square-py...

Abstract Three neutral Cu(II)/? 4 -NNNO Schiff base complexes ( 1-3 ) were prepared from the (E)-4-nitro-2-(((2-(piperazin-1-yl)ethyl)imino)methyl)phenol, tetradentate (SB) ligand, and corresponding copper(II) salts. The new SB its fully characterized by CHN-EA, standard spectroscopic, thermal, fluorescence analyses. formation of was monitored EDX, FT-IR, UV-Vis. chromotropism studies reflected...
