Di-μ-nicotinamide-κ(2) N (1):O;κ(2) O:N (1)-bis-[aqua-bis-(3-chloro-benzoato-κ(2) O,O')cadmium].

ABSTRACT: In the centrosymmetric dinuclear title compound, [Cd2(C7H4ClO2)4(C6H6N2O)2(H2O)2], the Cd(II) atom is coord-inated by one N atom from one bridging nicotinamide ligand and one O atom from another symmetry-related bridging nicotinamide ligand, four O atoms from two 3-chloro-benzoate ligands and one water mol-ecule in an irregular geometry. The dihedral angles between the carboxyl-ate groups and the adjacent benzene rings are 6.98 (12) and 2.42 (13)°, while the benzene rings are oriented at a dihedral angle of 4.33 (6)°. Inter-molecular O-H⋯O, N-H⋯O and weak C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network. π-π inter-actions, indicated by short centroid-centroid distances [3.892 (1) Å between the pyridine rings and 3.683 (1) Å between the benzene rings] further stabilize the structure.

Project description:In the title compound, [K2(C7H3Cl2O2)2(H2O)] n , the potassium salt of 2,4-di-chloro-benzoic acid, the repeating unit in the polymeric structure consists of two identical irregular KO6Cl units related by twofold rotational symmetry, linked by a bridging water mol-ecule lying on the twofold axis. The coordination polyhedron about the K(+) ion comprises a carboxyl-ate O atom and a Cl-atom donor from a bidentate chelate ligand inter-action, four O-atom donors from a doubly bridging bidentate carboxyl-ate O,O'-chelate inter-action and the water mol-ecule. A two-dimensional polymeric structure lying parallel to (100) is generated through a series of conjoined cyclic bridges between K(+) ions and is stabilized by water-carboxyl-ate O-H⋯O hydrogen-bonding inter-actions.

Project description:In the title complex, [Co(C7H4ClO2)2(C6H6N2O)2(H2O)2], the Co(II) atom is located on an inversion center and is coordinated by two 3-chloro-benzoate (CB) anions, two nicotinamide (NA) ligands and two water mol-ecules. The four O atoms in the equatorial plane form a slightly distorted square-planar arrangement, while the slightly distorted octa-hedral coordination is completed by the two N atoms of the NA ligands in the axial positions. The dihedral angle between the carboxyl-ate group and the adjacent benzene ring is 9.14 (9)°, while the pyridine and benzene rings are oriented at a dihedral angle of 82.18 (8)°. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds link the mol-ecules into a two-dimensional network lying parallel to (101). π-π stacking between parallel pyridine rings of adjacent mol-ecules [centroid-centroid distance = 3.7765 (8) Å] further stabilizes the crystal structure.

Project description:In the title complex, [Cd(C(7)H(4)ClO(2))(2)(H(2)O)](n), the Cd atom lies on a twofold axis and adopts a square-pyramidal coordination geometry. The water mol-ecule occupies the axial site with O atoms from four different 4-chloro-benzoato ligands in the equatorial plane. Pairs of 4-chloro-benzoato ligands bridge adjacent Cd(II) ions, generating an infinite chain structure along the c axis. Parallel polymeric chains are further inter-connected through water-acetate O-H⋯O hydrogen bonds, forming layers in the bc plane.

Project description:In the dinuclear centrosymmetric title compound, [Cd2(C8H7O2)4(C6H6N2O)2(H2O)2], the Cd(II) ion is chelated by two carboxyl-ate groups from 4-methyl-benzoate anions, and is further coordinated by one nicotinamide and one water mol-ecule; a carboxyl-ate O atom from an adjacent 4-methyl-benzoate anion bridges to the Cd(II) ion, completing the irregular coordination sphere of the seven ligand atoms. In the crystal, inter-molecular O-H⋯O, N-H⋯O and weak C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network. The methyl-benzene moiety of one bridging 4-methyl-benzoate anion is disordered over two orientations of equal occupancy.

Project description:In the crystal of the title Cd(II) polymeric complex, [Cd(C7H4ClO2)2(C10H14N2O)(H2O)] n , the Cd(II) cation is chelated by two chloro-benzoate anions and coordinated by two N,N-di--ethyl-nicotinamide (DENA) ligands and one water mol-ecule in a distorted NO6 penta-gonal-bipyramidal geometry.

Inter-molecular O-H⋯O hydrogen bonds between coordinating water mol-ecules and carboxyl-ate groups link adjacent chains into layers parallel to the bc plane. π-π contacts between benzene rings [shortest centroid-centroid distance = 3.912 (2) Å] further stabilizes the crystal structure. In the mol-ecule, weak C-H⋯O hydrogen bonds occur between the pyridine ring and carboxyl-ate groups; the dihedral angles between the carboxyl-ate groups and adjacent benzene rings are 4.6 (3) and 12.8 (3)°, while the benzene rings are oriented at a dihedral angle of 1.89 (13)°.

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.

Crystal structure of trans-di-aqua-bis-(4-cyano-benzoato-κO)bis-(N,N-di-ethyl-nicotinamide-κN)cadmium.

Project description:The mononuclear title cadmium complex, [Cd(C10H14N2O)2(C8H4NO2)2(H2O)2], is centrosymmetric and contains two water mol-ecules, two 4-cyanobenzoate (CB) ligands and two di-ethyl-nicotinamide (DENA) ligands. All the ligands are coordinated to the CdII atom in a monodentate mode. The four nearest O atoms around the CdII atom form a slightly distorted square-planar arrangement, with the distorted octa-hedral coordination sphere being completed by the two pyridine N atoms of the DENA ligands at distances of 2.3336 (13) Å. The dihedral angle between the carboxyl-ate group and the adjacent benzene ring is 8.75 (16)°, while the benzene and pyridine rings are oriented at a dihedral angle of 57.83 (5)°. The water mol-ecules exhibit both intra-molecular [to the non-coordinating carboxyl-ate O atom, enclosing an S(6) hydrogen-bonding motif, where O⋯O = 2.670 (2) Å] and inter-molecular [to the amide carbonyl O atom, enclosing an R22(16) ring motif, where O⋯O = 2.781 (2) Å] O-H⋯O hydrogen bonds. The latter lead to the formation of supra-molecular chains propagating along [110].

Inter-molecular O-H⋯O, N-H⋯O and weak C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network. π-π inter-actions, indicated by short centroid-centroid distances [3.845 (2) Å between the benzene rings, 3.650 (2) Å between the pyridine rings and 3.700 (3) Å between the benzene and pyridine rings] further stabilize the structure.
