Catena-Poly[bis-(4-amino-pyridinium) [[diaqua-manganese(II)]-di-?-chlorido] dichloride].

ABSTRACT: Single crystals of the title organic-inorganic hybrid, {(C(5)H(7)N(2))(2)[MnCl(2)(H(2)O)(2)]Cl(2)}(n), were synthesized from an ethanol solution containing manganese(II) chloride tetra-hydrate and 4-amino-pyridine under acidic conditions. The asymmetric unit contains a disordered organic cation (occupancies in the ratio 0.72:0.28), a chloride anion and an MnCl(H(2)O) moiety with the Mn(II) atom located on an inversion center. The structure is built up of infinite chains of edge-sharing [MnCl(4)(H(2)O)(2)] octa-hedra developing parallel to the a axis which are separated by the 4-amino-pyridinium ions and discrete chloride ions. The organic cations occupy the empty space around each inorganic chain. Structural cohesion is organized through N-H?Cl and O-H?Cl hydrogen bonds, which build up a three-dimensional network.

Project description:In the polymeric title complex, {[Ni(C(2)H(5)NO(2))(2)(H(2)O)(2)]Cl(2)}(n), the Ni(II) atom lies on an inversion center and is in a distorted octa-hedral NiO(6) configuration, with four carboxyl-ate O atoms from four zwitterionic glycine mol-ecules forming the equatorial plane and two water O atoms occupying the axial positions. The Cl(-) counterions lie in the inter-stices. The Ni(II) complexes are linked into polymeric sheets parallel to the bc plane. These sheets are then further connected into a three-dimensional network by O-H?O, O-H?Cl and N-H?Cl hydrogen bonds, together with weak C-H?O inter-actions.

Project description:In the title coordination polymer, [MnCl2(C7H5NS)2] n , the Mn(II) ion is located on the inter-section of a twofold rotation axis and a mirror plane and adopts an octa-hedral coordination geometry defined by two mutually trans N atoms from benzo-thia-zole ligands which occupy the axial positions, and four Cl atoms which form the equatorial sites. The Mn(II) ions are connected by two bridging Cl atoms, forming chains parallel to the c axis. The crystal packing can be descibed as alternating layers parallel to (001) featuring ?-? stacking inter-actions with a centroid-centroid distance of 3.6029?(15)?Å.

Project description:In the title compound, [Cd(2)Cl(6)(C(4)H(10)NO)(2)](n), the coordination geometry of each Cd(II) ion is distorted octa-hedral, but with quite different coordination environments. One Cd(II) atom is coordinated by four Cl atoms and two O atoms from two morpholinium ligands, while the other is coordinated by six Cl atoms. Adjacent Cd(II) atoms are inter-connected alternately by paired chloride bridges, generating a chain parallel to the a axis. Inter-chain N-H?Cl inter-actions form a two-dimensional network.

Project description:In the crystal structure of the title complex, {[Mn(C(11)H(14)NO(2))(2)(H(2)O)(3)]·2H(2)O}(n), the two independent Mn(II) atoms are located on a centre of symmetry and coordinated by two 4-(diethyl-amino)benzoate (DEAB) anions and two water mol-ecules in the basal plane while another water mol-ecule bridges the Mn atoms in the apical directions, forming polymeric chains. The dihedral angles between the carboxyl-ate groups and the adjacent benzene rings are 11.33?(13) and 10.90?(9)° and the benzene rings are oriented at a dihedral angle of 67.88?(6)°. The uncoordinated water mol-ecules link the carboxyl-ate groups and coordinated water mol-ecules via O-H?O hydrogen bonding. Weak C-H?? inter-actions are also found in the crystal structure.

Project description:The title complex, [CdCl(2)(C(9)H(12)N(4))](n), is characterized by the formation of a zigzag chain structure parallel to [001].

catena-Poly[[bis[quinazolin-4(3H)-one-?N]cadmium(II)]-di-?-chlorido].

Project description:The asymmetric unit of the title compound, [CdCl(2)(C(8)H(6)N(2)O)(2)](n), consists of one mol-ecule of the 3H-quinazolin-4-one ligand, one Cd(2+) cation, which is located on a twofold axis, and one chlorido ligand in a general position. The latter bridges metal cations, forming a one-dimensional polymer along the b axis. The Cd?Cd distance along the chain is 3.7309?(7)?Å. The octa-hedral coordination around the metal is completed by two ligands in a trans axial geometry which coordinate through the N atom in 1 position. Moderately strong classical N-H?O hydrogen bonds around crystallographic inversion centers cross-link adjacent polymeric chains.

Crystal structure, Hirshfeld surface analysis and physicochemical characterization of bis-[4-(di-methyl-amino)-pyridinium] di-μ-chlorido-bis[di-chlorido-mercurate(II)].

Project description:The title mol-ecular salt, (C7H11N2)2[Hg2Cl6], crystallizes with two 4-(di-methyl-amino)-pyridinium cations (A and B) and two half hexa-chlorido-dimercurate(II) anions in the asymmetric unit. The organic cations exhibit essentially the same features with an almost planar pyridyl ring (r.m.s. deviations of 0.0028 and 0.0109 Å), which forms an inclined dihedral angle with the dimethyamino group [3.06 (1) and 1.61 (1)°, respectively]. The di-methyl-amino groups in the two cations are planar, and the C-N bond lengths are shorter than that in 4-(di-methyl-amino)-pyridine. In the crystal, mixed cation-anion layers lying parallel to the (010) plane are formed through N-H⋯Cl hydrogen bonds and adjacent layers are linked by C-H⋯Cl hydrogen bonds, forming a three-dimensional network. The analyses of the calculated Hirshfeld surfaces confirm the relevance of the above inter-molecular inter-actions, but also serve to further differentiate the weaker inter-molecular inter-actions formed by the organic cations and inorganic anions, such as π-π and Cl⋯Cl inter-actions. The powder XRD data confirms the phase purity of the crystalline sample. Furthermore, the vibrational absorption bands were identified by IR spectroscopy and the optical properties were studied by using optical UV-visible absorption spectroscopy.
