Crystal structure of poly[bis-(?2-5-hydroxy-nicotinato-?(2) N:O (3))zinc].

ABSTRACT: The title coordination polymer, [Zn(C6H4NO3)2] n , was prepared under hydro-thermal conditions by the reaction of zinc nitrate with 5-hy-droxy-nicotinic acid in the presence of malonic acid. In the structure, the Zn(II) ion is coordinated by two carboxyl-ate O atoms and two pyridine N atoms of four 5-hy-droxy-nicotinate ligands in a distorted tetra-hedral coordin-ation environment. The ?2-bridging mode of each anion leads to the formation of a three-dimensional framework structure. Inter-molecular hydrogen bonds between the hy-droxy groups of one anion and the non-coordinating carboxyl-ate O atoms of neighbouring anions consolidate the crystal packing.

Poly[?-azido-(?(3)-nicotinato N-oxide)zinc(II)].

Project description:The title compound, [Zn(C(6)H(4)NO(3))(N(3))], has been prepared by the reaction of nicotinate N-oxide acid, zinc(II) nitrate and sodium azide. The Zn atom is five coordinated by two azide anions and three nicotinate N-oxide ligands. Each nicotinate N-oxide bridges three Zn atoms, whereas the azide bridges two Zn atoms, resulting in the formation of a two-dimensional metal-organic polymer developing parallel to (100).

Crystal structure of poly[bis-(?-nicotinamide-?(2) N (1):O)bis-(?-4-nitro-benzoato-?(2) O (1):O (1'))zinc].

Project description:The asymmetric unit of the title coordination polymer, [Zn(C7H4NO4)2(C6H6N2O)2] n , contains two 4-nitro-benzoate (NB) anions and two nicotinamide (NA) ligands. The Zn(II) atom has a slightly distorted octa-hedral coordination sphere. In the equatorial plane, it is coordinated by three carboxyl-ate O atoms of the NB anions and one O atom of one of the two NA ligands. The axial positions are occupied by the pyridine N atoms of the two NA ligands. In the two NB anions, the carboxyl-ate groups are twisted away from the attached benzene rings by 13.8?(2) and 13.4?(2)°, while the benzene rings are oriented at a dihedral angle of 11.5?(2)°. The dihedral angle between the NA rings is 10.3?(1)°. Only one of the two NB anions and one of the two NA ligands bridge adjacent Zn(II) ions through eight- and twelve-membered rings, respectively, forming polymeric chains running along the a-axis direction. In the crystal, N-H ? O hydrogen bonds link adjacent chains, enclosing R(16), R 2 (2)(20) and R 6 (6)(16) ring motifs, forming layers parallel to (01-1). The layers are linked via a number of C-H?O hydrogen bonds, forming a three-dimensional network.

Poly[(?(3)-5-bromo-nicotinato)(5-bromo-nicotinato)copper(II)].

Project description:The title coordination polymer, [Cu(C(6)H(3)BrNO(2))(2)](n), is composed of two structurally similar two-dimensional coordination polymers (twin layers). Both of them have the same chemical composition but they display different bond lengths and angles. In each layer, two N atoms and four carboxyl-ate O atoms from the bridging 5-bromo-nicotinate ligands and four carboxyl-ate O atoms from the terminal 5-bromo-nicotinate ligands bind to two Cu(II) atoms to form a dinuclear paddle-wheel-like pattern. Adjacent paddle wheels are further linked by bridging 5-bromo-nicotinate groups to generate a two-dimensional coordination polymer; neighboring twin-like layers are finally stacked through ?-? stacking interactions between adjacent pyridine rings [perpendicular distance of 3.626?(2)?Å] in a 'sandwich' manner, thus generating a three-dimensional supra-molecular structure.

Crystal structure of di-chlorido-bis-(4-ethyl-aniline-?N)zinc.

Project description:The title compound, [ZnCl2(C8H11N)2], was synthesized by the reaction of zinc dichloride and 4-ethyl-aniline. The Zn(2+) cation is coordinated by two Cl(-) anions and the N atoms of two 4-ethyl-aniline ligands, forming a distorted Zn(N2Cl2) tetra-hedron. The dihedral angle between the two benzene rings is 85.3?(2)° The Zn atom lies on a twofold rotation axis. The ethyl substituents are disordered over two sets of sites in a 0.74?(2):0.26?(2) ratio. In the crystal, N-H?Cl hydrogen bonds link the mol-ecules into sheets perpendicular to the a axis. C-H?Cl inter-actions also occur.

Crystal structure of dimanganese(II) zinc bis-[ortho-phosphate(V)] monohydrate.

Project description:The title compound, Mn2Zn(PO4)2·H2O, was obtained under hydro-thermal conditions. The structure is isotypic with other transition metal phosphates of the type M 3- xM' x (PO4)2·H2O, but shows no statistical disorder of the three metallic sites. The principal building units are distorted [MnO6] and [MnO5(H2O)] octa-hedra, a distorted [ZnO5] square pyramid and two regular PO4 tetra-hedra. The connection of the polyhedra leads to a framework structure. Two types of layers parallel to (-101) can be distinguished in this framework. One layer contains [Zn2O8] dimers linked to PO4 tetra-hedra via common edges. The other layer is more corrugated and contains [Mn2O8(H2O)2] dimers and [MnO6] octa-hedra linked together by common edges. The PO4 tetra-hedra link the two types of layers into a framework structure with channels parallel to [101]. The H atoms of the water mol-ecules point into the channels and form O-H?O hydrogen bonds (one of which is bifurcated) with framework O atoms across the channels.

Crystal structure of bis-(piperazin-1-ium-?N4)bis-(thio-sulfato-?S)zinc(II) dihydrate.

Project description:In the title compound, [Zn(C4H11N2)2(S2O3)2]·2H2O, two thio-sulfate ions coordinate to the zinc(II) atom through the terminal S atoms. The tetra-hedral coordination around the ZnII ion is completed by ligating to two N atoms of two piperazinium ions. The remaining two N atoms of the piperazinium ions are diprotonated and do not coordinate to the metal centre. In the crystal, however, they are involved in N-H?Owater and N-H?Osulfato hydrogen bonds. Together, a series of N-H?O and O-H?O hydrogen bonds, involving the O atoms of the thio-sulfate ions and the water mol-ecules as acceptors and the hydrogen atoms of the piperazinium ions and the water mol-ecules as donors, form a three-dimensional supra-molecuar structure. Within this framework there are a number of intra- and inter-molecular C-H?O and C-H?S contacts present.

Crystal structure of bis-(isonicotinamide-?N (1))bis-(thio-cyanato-?N)zinc.

Project description:The asymmetric unit of the title complex, [Zn(SCN)2(C6H6N2O)2], consists of one Zn(2+) cation located on a twofold rotation axis, as well as of one thio-cyanate anion and one neutral isonicotinamide ligand, both occupying general positions. The Zn(2+) cation is tetra-hedrally coordinated into a discrete complex by the N atoms of two symmetry-related thio-cyanate anions and by the pyridine N atoms of two isonicotinamide ligands. The complexes are linked by inter-molecular C-H?O and N-H?O, and weak inter-molecular N-H?S hydrogen-bonding inter-actions into a three-dimensional network.
