Tetra-kis(?-3-chloro-benzoato-?(2) O:O')bis-[(N,N-di-ethyl-nicotinamide-?N (1))copper(II)].

ABSTRACT: In the title centrosymmetric binuclear Cu(II) complex, [Cu2(C7H4ClO2)4(C10H14N2O)2], the two Cu(II) cations [Cu?Cu = 2.6314?(4)?Å] are bridged by four 3-chloro-benzoate (CB) anions. The four carboxyl-ate O atoms around each Cu(II) cation form a distorted square-planar arrangement, the distorted square-pyramidal coordination geometry being completed by the pyridine N atom of the N,N-di-ethyl-nicotinamide (DENA) mol-ecule. The dihedral angle between the benzene ring and the carboxyl-ate group is 4.49?(11)° in one of the independent CB ligands and 12.00?(10)° in the other. The benzene rings of the independent CB ligands are oriented at a dihedral angle of 84.13?(6)°. In the crystal, weak C-H?O hydrogen bonds link the binuclear complex mol-ecules into supra-molecular chains running along [101].

Project description:The mol-ecule of the title Cu(II) complex, [Cu(C7H4ClO2)2(C6H6N2O)2], contains two 3-chloro-benzoate (CB) and two nicotinamide (NA) ligands; the CB act as bidentate ligands, while the NA are monodentate ligands.

Crystal structure of tetra-kis-(μ-2,4,6-tri-methyl-benzoato-κ(2) O:O')bis-[(nicotinamide-κN (1))copper(II)].

Project description:In the title binuclear Cu(II) complex, [Cu2(C10H11O2)4(C6H6N2O)2], the two Cu(II) cations [Cu⋯Cu = 2.5990 (5) Å] are bridged by four 2,4,6-tri-methyl-benzoate (TMB) anions.

The Cu(II) cations are displaced by -0.2045 (3) and 0.2029 (3) Å from the corresponding planes formed by the nearest four O atoms. In the mol-ecule, the dihedral angles between the planes of the benzene rings and the adjacent carboxyl-ate groups are 80.6 (2), 51.4 (2), 24.4 (2) and 32.5 (2)°, while the planes of the pyridine rings are oriented at a dihedral angle of 11.28 (10)°. In the crystal, bifurcated N-H⋯O and weak C-H⋯O hydrogen bonds link the mol-ecules, enclosing R 2 (2)(8) and R 4 (4)(8) ring motifs, into a three-dimensional network. The structure contains a solvent-accessible void of 72 Å(3), but there is no solvent mol-ecule located within this void. The crystal studied was an inversion twin refined with a minor component of 0.488 (8).

Project description:In the title centrosymmetric dinuclear compound, [Cu(2)(C(8)H(7)O(2))(4)(C(8)H(8)O(2))(2)], four o-toluate anions form a cage around two Cu atoms in a syn-syn configuration.

The acid H atoms are hydrogen bonded to the cage carboxyl O atoms [O⋯O = 2.660 (2) Å]. The mol-ecular packing forms a puckered pseudo-hexa-gonal close-packed layer in the (h00) plane, with soft inter-molecular H⋯H contacts (2.46-2.58 Å).
