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

Abstract

Two new transition metal complexes [Cu(4-Cbsgly)(phen)]·0.5H 2 O (1),[Ni(4-Cbsgly)(phen) 2 ]·3H 2 O (2) [4-CbsglyH 2 = (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.

Crystal structure of poly-[(μ2-(carboxylatomethyl)((3-nitrophenyl)sulfonyl)amido-κ3 N:O:O′)(μ2-4,4′-bipyridine-κ2 N:N′) nickel(II)], C18H14NiN4O6S

“…The sulfonylated amino acid has a plurality of coordination sites because it contains both an amino group and a carboxyl group. It can be used to assemble MOFs and CPs [5][6][7][8] which have potential applications in gas adsorption and separations [9][10][11], sensors [12,13], catalysis [14,15], and fluorescent materials [16].…”

Crystal structure of poly-[(μ2(carboxylatomethyl)((3-nitrophenyl)sulfonyl)amido-κ3 N: O:O′)(μ2-4,4′-bipyridine-κ2 N:N′)copper(II)], C18H14CuN4O6S

“…In recent years, it has gained great attention due to their diverse structures and rich physical and chemical properties, such as electricity, light, and magnetism etc., and potential applications in gas adsorption/storage and separation [5][6][7][8], identification and sensing [9][10][11], and heterogeneous catalysis [12,13]. The sulfonylated amino acid compound which has some coordination sites can be used to assemble metal organic frameworks and coordination polymers [14][15][16][17]. In this paper, the synthesis and crystal structure of a new copper(II) complex with 3-nitrobenzenesulfonylglycine (H 2 nbs) and 4,4′-bipyridine (4,4′-bipy) is reported.…”

“…The asymmetric unit is composed of one independent Cu(II) ion, one nbs ligand and one 4,4′-bipy ligand. The crystallographically unique Cu 2+ ion of the title complex is fivecoordinated (see the figure) by two N atoms (N3, N4) from 4,4′-bipy group, two O atoms (O1, O2) and one N atom (N1) from nbs group (Cu1-O, 1.9549 (15)…”
