Project description:In the title mononuclear complex, [Cd(C(8)H(7)O(2))(2)(H(2)O)(2)], the Cd(II) atom possesses crystallographically imposed C(2) site symmetry, and is coordinated by four O atoms from two 4-methyl-benzoate ligands and two water mol-ecules, displaying a distorted octa-hedral geometry. The molecules are assembled via inter-molecular O-H⋯O hydrogen-bond inter-actions into a supra-molecular architecture.

Project description:The title Zn(II) complex, [Zn(C(7)H(4)BrO(2))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(2)], is centrosymmetric with the Zn atom on an inversion center. The mol-ecule contains two 2-bromo-benzoate (BB) and two nicotinamide (NA) ligands and two coordinated water mol-ecules, all ligands being monodentate. The four O atoms in the equatorial plane around the Zn atom 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 group and the adjacent benzene ring is 31.14 (12)°, while the pyridine and benzene rings are oriented at a dihedral angle of 83.54 (5)°. In the crystal structure, O-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules into infinite chains. A weak C-H⋯π inter-action is also present.

Project description:The title Ni(II) complex, [Ni(C(8)H(8)NO(2))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(2)], is centrosymmetric with the Ni atom on an inversion center. The mol-ecule contains two 4-methyl-amino-benzoate (MAB) and two nicotinamide (NA) ligands and two coordinated water mol-ecules, all ligands being monodentate. The four O atoms in the equatorial plane around the Ni atom 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 2.09 (14)°, while the pyridine and benzene rings are oriented at a dihedral angle of 66.15 (4)°. In the crystal structure, inter-molecular O-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.

Project description:In the centrosymmetric title complex, [Zn(C(7)H(4)BrO(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], the Zn(II) atom is located on an inversion center. The asymmetric unit contains one 2-bromo-benzoate (BB), one diethyl-nicotinamide (DENA) ligand and one coordinating water molecule. The four O atoms in the equatorial plane around the Zn atom form a slightly distorted square-planar arrangement, while the slightly distorted octa-hedral coordination is completed by the two N atoms of the DENA ligands in the axial positions. The dihedral angle between the carboxyl group and the adjacent benzene ring is 85.51 (12)°, while the pyridine and benzene rings are oriented at a dihedral angle of 44.07 (6)°. In the crystal structure, O-H⋯O hydrogen bonds link the mol-ecules into infinite chains.

Project description:In the title compound, [Ni(C(8)H(5)O(4))(2)(H(2)O)(2)], the Ni(II) atom lies on an inversion centre and exhibits a square-planar geometry incorporating two phthalate and two water O atoms. The nickel complex is stabilized by intra-molecular inter-actions involving water O atoms and H atoms of the phthalate groups. It forms one-dimensional zigzag chains along the b axis which are held together via π-π stacking inter-actions (3.647 Å) between the benzene rings of the phthalate groups. The adjacent chains are also hydrogen bonded, resulting in a three-dimensional supra-molecular network.

Project description:The title mononuclear complex mol-ecule, [Zn(C(7)H(4)BrO(3))(2)(C(7)H(8)N(2)O)(2)(H(2)O)(2)], has a crystallographically imposed centre of symmetry. The zinc(II) atom is coordinated by two N atoms from two N-methyl-nicotinamide ligands, two O atoms from two 5-bromo-salicylate anions and two aqua O atoms in a slightly distorted octa-hedral geometry. Intra-molecular O-H?O hydrogen-bonding inter-actions are present. In the crystal structure, mol-ecules are linked by inter-molecular O-H?O and N-H?O hydrogen bonds, forming a two-dimensional network perpendicular to [100].

Project description:The title Ni(II) complex, [Ni(C(7)H(4)ClO(2))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(2)], is centrosymmetric with the Ni atom located on an inversion centre. The mol-ecule contains two 2-chloro-benzoate (CB) and two nicotinamide (NA) ligands and two water mol-ecules, all ligands being monodentate. The four O atoms in the equatorial plane around the Ni atom 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 group and the adjacent benzene ring is 29.48 (16)°, while the pyridine and benzene rings are oriented at a dihedral angle of 83.16 (5)°. In the crystal structure, O-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules into infinite chains. π-π Contacts between the benzene and pyridine rings [centroid-centroid distance = 3.952 (1) Å] may further stabilize the crystal structure. There is also a C-H⋯π inter-action.

Project description:The title compound, [Zn(C(8)H(7)O(4))(2)(H(2)O)(2)], has been synthesized by hydro-thermal methods. The Zn(II) atom, whose symmetry element is a twofold axis, is four coordinated by two O atoms from 5-meth-oxy-salicylate anions and two aqua O atoms in a distorted tetra-hedral geometry. In the crystal, mol-ecules are linked into a layer by O-H⋯O hydrogen bonds, which stabilize the packing.
