Abstract

Tetra–μ–[N-phenylanthranilato](O,O′)–bis[2-amino-4-methyl) pyridine copper(II)] (bisdichloromethane solvate and unsolvate) in one crystalline contains two independent binuclears, one of which is unsolvate and the other one is dichloromethane solvate. The phenyl ring planes in the asymmetric units were not parallel to each other [44.47(14)° and 52.50(13)° for unsolvate unit, 53.30(14)° and 49.59(13)° for solvate unit] and the distance between the two centers of phenyl rings was measured as 5.064 Å (for Cg2-Cg3), 5.005 Å (for Cg4-Cg5), 5.048 Å (for Cg7-Cg8), and 5.088 Å (for Cg9-Cg10) for NPA ligands. The complex molecules showed three dimensional supramolecular networks by O–H···O, C–H···O, C–H···π, and π···π interactions. [ABSTRACT FROM AUTHOR]

Abstract

The complexes, tetra-μ-[2-(phenylamino)benzoato](O,O′)-bis[(ethanol)copper(II)] (1) and di-μ-[2-(phenylamino)benzoato](O,O′)-bis[(hydroxo)copper(II)] (2), were synthesized by the reaction of N-phenylanthranilic acid and CuCl2·2H2O in an ethanol water mixture. In complex 1, each Cu(II) atom, which is in a slightly distorted square pyramidal environment, is coordinated equatorially by four N-phenylanthranilate O-atoms and axially by the ethanol O-atoms. In complex 2, [Cu2(C6H5NHC6H4COO)2(OH)2], each Cu(II) atom, which is in tetrahedral environment, is coordinated by two N-phenylanthranilate O-atoms and hydroxo ligands. The crystal structure (monoclinic, P21/c space group) of complex 1 comprises a dinuclear [Cu2(C6H5NHC6H4COO)4(CH3CH2OH)2] species and the dimer is located on a crystallographic inversion centre. The Cu(II) ions, 2.591(2) Å apart, are bridged by the carboxylate groups of four N-phenylanthranilate ligands. The complex molecules show three-dimensional supramolecular networks by O–H···O, C–H···O and C–H···π interactions. [ABSTRACT FROM AUTHOR]

Abstract

WOS: 000317249500005, The complex, tetrakis-mu-[2-(phenylamino)benzoato](O,O')-bis[4-vinylpyridine copper(II)] (1) was synthesized by the reaction of N-phenylanthranilic acid and copper powder in the presence of 4-vinylpyridine and crystallized from ethanol-dichloromethane-n-hexane mixture (1: 1: 1). The crystal structure of 1 contains one binuclear cage complex and each dimer locate on a crystallographic inversion centre (triclinic, P (1) over bar space group). In the compound, two Cu(II) ions are bridged by four mu(2)-O-O' N-phenylanthranilato (NPA) ligands, forming a cage structure, and 4-vinylpyridine ligands are bonded through their N atoms to the Cu(II) ions in terminal positions to form square pyramidal environment around Cu(1) ions. The Cu(II) ions in apart of 2.6298(14) angstrom, are bridged by the carboxylate groups of four N-phenylanthranilate ligands. The complex molecules show three dimensional supramolecular networks by O-H center dot center dot center dot O, C-H center dot center dot center dot O, C-H center dot center dot center dot pi and pi center dot center dot center dot pi interactions.
