Bis(isonicotinamide-?N)bis-(4-methyl-benzoato-?O)copper(II) dihydrate.

ABSTRACT: In the centrosymmetric title compound, [Cu(C(8)H(7)O(2))(2)(C(6)H(6)N(2)O)(2)]·2H(2)O, the Cu(II) ion is located on a crystallographic inversion center. The asymmetric unit is completed by one 4-methyl-benzoate anion, one isonicotinamide (INA) ligand and one uncoordinated water mol-ecule; all the ligands are monodentate. The two O and the two N atoms around the Cu(II) ion form a slightly distorted square-planar arrangement. The dihedral angle between the carboxyl-ate group and the attached benzene ring is 13.86?(9)°, while the pyridine and benzene rings are oriented at a dihedral angle of 86.08?(5)°. The uncoordinated water mol-ecules are linked to the INA ligands by O-H?O hydrogen bonds. In the crystal structure, inter-molecular O-H?O, N-H?O and C-H?O hydrogen bonds link the mol-ecules into a three-dimensional network.

Project description:In the title centrosymmetric binuclear complex, [Cu(2)(C(8)H(7)O(2))(4)(C(6)H(6)N(2)O)(2)], the Cu atoms [Cu?Cu = 2.6375?(6)?Å] are bridged by four 4-methyl-benzoate (PMB) ligands. The four nearest O atoms around each Cu(II) ion form a distorted square-planar arrangement, and the distorted square-pyramidal coordination is completed by the pyridine N atom of the isonicotinamide (INA) ligand. Each Cu(II) ion is displaced by 0.2633?(1)?Å from the plane of the four O atoms, with an average Cu-O distance of 1.974?(2)?Å. The dihedral angles between carboxyl-ate groups and the adjacent benzene rings are 7.88?(19) and 9.68?(10)°, while the benzene rings are oriented at a dihedral angle of 85.90?(9)°. The pyridine ring is oriented at dihedral angles of 8.59?(7) and 83.89?(9)° with respect to the benzene rings. In the crystal structure, inter-molecular N-H?O hydrogen bonds link the mol-ecules into a three-dimensional network. ?-? contacts between the benzene rings and between the pyridine and benzene rings, [centroid-centroid distances = 3.563?(2) and 3.484?(2)?Å, respectively] may further stabilize the crystal structure.

Project description:In the title Zn(II) complex, [Zn(C(8)H(8)NO(2))(2)(C(6)H(6)N(2)O)(2)]·H(2)O, the Zn atom is coordinated by two 4-methyl-amino-benzoate (MAB) and two isonicotinamide (INA) ligands in a distorted trigonal-bipyramidal geometry; one of the MAB ions acts as a bidentate ligand while the other MAB and the two INA are monodentate ligands. The dihedral angles between the carboxyl groups and the adjacent benzene rings are 8.52 (22) and 5.10 (14)°. In the crystal, inter-molecular O-H⋯O and N-H⋯O hydrogen bonding links the mol-ecules into a supra-molecular structure. Weak inter-molecular C-H⋯O inter-actions are also present.

Bis[2-(1H-benzimidazol-2-yl)benzoato]copper(II) dihydrate.

Project description:In the title compound, [Cu(C(14)H(9)N(2)O(2))(2)]·2H(2)O, the Cu(II) ion lies on a centre of symmetry and is four-coordinated by two N atoms and two O atoms from two 2-(1H-benzimidazol-2-yl)benzoate ligands in a square-planar environment. The benzimidazol and benzyl rings form a dihedral angle of 42.8 (5)°. The mol-ecule contains two H-bonded carboxyl O acceptors and two H-bonded N-H donors in the benzimidazol groups, which inter-act with two symmetry-related uncoordinated water mol-ecules so that neighboring mol-ecular units are linked by (O-H)(water)⋯O(carbox-yl) hydrogen bonds with an R(2) (4)(8) graph-set motif, generating a helical chain in the a-axis direction. These chains are, in turn, inter-connected by (N-H)(benzimidazol)⋯O(water) hydrogen bonds, forming a three-dimensional supra-molecular network.

Diaqua-bis[4-(dimethyl-amino)benzoato](isonicotinamide)zinc(II).

Project description:The mol-ecule of the title Zn(II) complex, [Zn(C(9)H(10)NO(2))(2)(C(6)H(6)N(2)O)(H(2)O)(2)], contains two 4-(dimethyl-amino)benzoate (DMAB) ligands, one isonicotinamide (INA) ligand and two water mol-ecules; one of the DMAB ions acts as a bidentate ligand while the other and INA are monodentate ligands. The four O atoms in the equatorial plane around the Zn atom form a distorted square-planar arrangement, while the distorted octa-hedral coordination is completed by the N atom of the INA ligand and the O atom of the water mol-ecule in the axial positions. Intra-molecular C-H?O hydrogen bonding results in the formation of a six-membered ring adopting an envelope conformation. The dihedral angle between the carboxyl groups and the adjacent benzene rings are 4.87?(16) and 2.2?(2)°, while the two benzene rings are oriented at a dihedral angle of 65.13?(8)°. The dihedral angle between the benzene and pyridine rings are 11.47?(7) and 74.83?(8)°, respectively. In the crystal structure, inter-molecular O-H?O, O-H?N and N-H?O hydrogen bonds link the mol-ecules into a supra-molecular structure. ?-? contacts between the pyridine and benzene rings and between the benzene rings [centroid-centroid distances = 3.695?(1) and 3.841?(1)?Å, respectively] further stabilize the structure. Weak inter-molecular C-H?? inter-actions are also present.

Bis(?(2)-2-chloro-benzoato-?O:O')bis-[(2-chloro-benzoato-?O)(1,10-phenanthroline-?N:N')copper(II)] dihydrate.

Project description:In the title compound, [Cu(2)(C(7)H(4)ClO(2))(4)(C(12)H(8)N(2))(2)]·2H(2)O, the two crystallographically independent dinuclear complex mol-ecules, A and B, have different Cu?Cu separations, viz. 3.286?(1)?Å in A and 3.451?(1)?Å in B. Both independent mol-ecules reside on inversion centres, so the asymmetric unit contains a half-mol-ecule each of A and B and two water mol-ecules. Each Cu atom has a square-pyramidal environment, being coordinated by two O atoms from two bridging 2-chloro-benzoate ligands, one O atom from a monodentate 2-chloro-benzoate ligand and two N atoms from a 1,10-phenanthroline ligand. The water mol-ecules can also be considered as coordinating ligands, which complete the coordination geometry up to distorted octa-hedral with elongated Cu-O distances, viz. 3.024?(3)?Å in A and 2.917?(3)?Å in B. In the crystal, weak inter-molecular C-H?O inter-actions contribute to the consolidation of the crystal packing.

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).

Project description:The asymmetric unit of the crystal structure of the title complex, [Co(C(6)H(6)N(2)O)(2)(H(2)O)(4)](C(8)H(5)O(3))(2)·2H(2)O, contains one-half of the complex cation with the Co(II) ion located on an inversion center, a 4-formyl-benzoate (FB) counter-anion and an uncoordinated water mol-ecule. The four O atoms in the equatorial plane around the Co(II) ion form a slightly distorted square-planar arrangement with an average Co-O bond length of 2.086 Å; the slightly distorted octa-hedral coordination is completed by the two N atoms of the isonicotinamide (INA) ligands at a slightly longer distance [2.1603 (14) Å] in the axial positions. The dihedral angle between the carboxyl-ate group and the attached benzene ring is 5.93 (13)°, while the pyridine and benzene rings are oriented at a dihedral angle of 3.09 (6)°.
