Syntheses, Crystal Structures, and Thermal Properties of Two Transition Metal Complexes With 4-Chlorobenzenesulfonyl-glycine Acid Ligand

Two new transition metal complexes [Cu(4-Cbsgly)(phen)]·0.5H2O (1), [Ni(4-Cbsgly)(phen)2]·3H2O (2) [4-CbsglyH2 = (4-chlorobenzenesulfonyl-glycine acid, phen = 1,10-phenanthroline) were synthesized and characterized by elemental analysis, IR, TG analysis, and single-crystal X-ray diffraction. The complexes 1 and 2 are assembled by various kinds of hydrogen bonds and π-π stacking interactions into the 1D chain and 2D layer, respectively. Two-dimensional layer in 2 are further connected to form sandwich-like structure through weak O–H···O and C–H···O interactions. Furthermore, the thermal stability of complexes 1 and 2 were investigated.
