Poly[[bis-(?-3-amino-5-carb-oxy-benzoato-?(2)N:O(1))diaqua-zinc] dihydrate].

ABSTRACT: The Zn(II) atom in the title polymeric compound, {[Zn(C(8)H(6)NO(4))(2)(H(2)O)(2)]·2H(2)O}(n), lies on a center of inversion and is coordinated by two amine N atoms and two carboxyl-ate O atoms from two 3-amino-5-carb-oxy-benzoate anions along with two water mol-ecules in a distorted octa-hedral geometry. The bridging nature of the anion generates a layer motif parallel to (100). Hydrogen bonds of the N-H?O and O-H?O types exist in the structure. One H atom of the coordinated water mol-ecule and one H atom of the solvent water mol-ecule are each disordered over two positions in a 1:1 ratio.

Project description:In the centrosymmetric title structure, [Zn(C(9)H(10)NO(2))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(2)]·2H(2)O, the Zn(II) cation, located on an inversion center, is coordinated by two 4-(methyl-amino)-benzoate anions, two nicotinamide ligands and two water mol-ecules in a slightly distorted octa-hedral geometry. The dihedral angle between the carboxyl-ate group and the attached benzene ring is 3.09?(9)°, while the pyridine and benzene rings are oriented at a dihedral angle of 77.10?(4)°. The uncoordinated water mol-ecule is linked to nicotinamide ligands by O-H?O hydrogen bonds. In the crystal, inter-molecular N-H?O, O-H?O and C-H?O hydrogen bonds link the mol-ecules into a three-dimensional network. A weak N-H?? inter-action also occurs.

Diaqua-bis-(4-meth-oxy-benzoato-?O)bis-(nicotinamide-?N)nickel(II) dihydrate.

Project description:In the mononuclear title compound, [Ni(C(8)H(7)O(3))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(2)]·2H(2)O, the Ni(II) ion is located on a crystallographic inversion center. The asymmetric unit further contains one 4-meth-oxy-benzoate anion, one nicotinamide (NA) ligand and one coordinated and one uncoordinated water mol-ecule; all ligands are monodentate. The four O atoms in the equatorial plane around the Ni(II) ion form a slightly distorted square-planar arrangement, while the slightly distorted octa-hedral coordination is completed by the two pyridine N atoms of the NA ligands in the axial positions. The dihedral angle between the carboxyl-ate group and the attached benzene ring is 7.2?(1)°, while the pyridine and benzene rings are oriented at a dihedral angle of 72.80?(4)°. An intra-molecular O-H?O hydrogen bond links the uncoordinated water mol-ecule to one of the carboxyl-ate groups. 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.

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.

Diaqua-bis-{2-hy-droxy-5-[(pyridin-2-yl)methyl-idene-amino]-benzoato-?N,N'}zinc(II) dihydrate.

Project description:The complex mol-ecule of the title compound, [Zn(C(13)H(9)N(2)O(3))(2)(H(2)O)(2)]·2H(2)O, has 2 symmetry with the Zn(II) cation located on a twofold rotation axis.

Within the anionic ligand, the pyridine ring is oriented at a dihedral angle of 49.54?(10)° with respect to the benzene ring. The carboxyl-ate group of the anionic ligand is not involved in coordination but is O-H?O hydrogen bonded to the coordinated and uncoordinated water mol-ecules. Weak inter-molecular C-H?O hydrogen bonding is also present in the crystal structure.

Diaqua-bis-(4-carb-oxy-2-ethyl-1H-imidazole-5-carboxyl-ato-κN,O)cadmium dihydrate.

Project description:The asymmetric unit of the title compound, [Cd(C(7)H(7)N(2)O(4))(2)(H(2)O)(2)]·2H(2)O, consists of one Cd(II) ion, one 4-carb-oxy-2-ethyl-1H-imidazole-5-carboxyl-ate anion, one coordinated water mol-ecule and one lattice water mol-ecule. The Cd(II) ion lies on a twofold axis, and is hexa-coordinated by four O atoms from water mol-ecules and carboxyl-ate groups and two N atoms from two imidazole rings, in a distorted octa-hedral arrangement. An extensive framework of N-H⋯O and O-H⋯O hydrogen bonds with the participation of coordinated and free water mol-ecules is found in the crystal structure, which contributes to the formation of a three-dimensional structure.

Project description:The crystal structure of the title compound, 2C(3)H(5)N(4)O(2) (+)·SO(4) (2-)·2H(2)O, displays a three-dimensional framework in which mixed infinite chains [oriented parallel to (510) and ([Formula: see text]10)] inter-fere, forming tunnels extending parallel to the c axis.
