Poly[(?(3)-benzene-1,3,5-tricarboxyl-ato-?O:O:O)(?(2)-2-methyl-imidazolato-?N:N')tris-(2-methyl-imidazole-?N)dizinc(II)].

ABSTRACT: Hydro-thermal reaction involving zinc nitrate hexa-hydrate, tris-odium benzene-1,3,5-tricarboxyl-ate (Na(3)BTC) and 2-methyl-imidazole (2-MeImH) yielded the title compound, [Zn(2)(C(9)H(3)O(6))(C(4)H(5)N(2))(C(4)H(6)N(2))(3)]. In this mixed-ligand metal-organic compound, Zn(2+) ions are coordinated by N atoms from 2-MeImH mol-ecules and (2-MeIm)(-) ions, as well as by O atoms from (BTC)(3-) ions. This results in two different distorted tetra-hedra, viz. ZnN(3)O and ZnN(2)O(2). These tetra-hedra are inter-connected via (BTC)(3-) ions and N:N'-bridging (2-MeIm)(-) ions, thus forming a layered structure in the bc plane. Hydrogen bonds between the O atoms of carboxyl-ate ions and NH groups of 2-MeImH ligands link the layers into a three-dimensional structure.

Project description:In the asymmetric unit of title coordination polymer, {(C(16)H(36)N)[Zn(3)(C(9)H(3)O(6))(2)(OH)]·0.25H(2)O}(n), there are three independent Zn(2+) cations, two benzene-1,3,5-tricarboxyl-ate ligands and a μ(3)-bridging hydroxide group, together with a tetra-n-butyl-ammonium counter-cation and a partially occupied water molecule of solvation (occupancy 0.25). Each Zn ion is coordinated by three carboxyl-ate O atoms and one O atom from the bridging hydroxide ion, displaying a slightly distorted tetra-hedral stereochemistry [overall Zn-O range = 1.875 (3)-1.987 (2) Å]. An intra-molecular hydrogen bond involving the hydroxide H atom and a carboxyl-ate O-atom acceptor is also present in the complex unit. The bridging benzene-1,3,5-tricarboxyl-ate anions generate a three-dimensional framework structure.

Project description:In the title compound, {[Zn(3)(C(9)H(3)O(6))(2)(H(2)O)(8)]·4H(2)O}(n), there are two crystallographically independent Zn(II) ions. One presents a trigonal-bipyramidal coordination geometry defined by five O atoms [three from two carboxyl-ate groups of two benzene-1,3,5-tricarboxyl-ate (BTC) ligands and the other two deriving from three water mol-ecules], while the other lies on an inversion centre and exists in a slightly distorted octa-hedral coordination geometry defined by six O atoms (two from two carboxyl-ate groups of two BTC ligands and the others from four water mol-ecules). A three-dimensional framework is further strengthened via O-H?O hydrogen-bonding inter-actons.

Poly[[aqua-?(6)-benzene-1,2,3-tricarboxyl-ato-?(3)-hydroxido-dizinc] hemihydrate].

Project description:In the title compound, {[Zn(2)(C(9)H(3)O(6))(OH)(H(2)O)]·0.5H(2)O}(n), there are three independent Zn(II) atoms present; two are located on special positions, viz a twofold rotation axis and an inversion centre, and the third is located in a general position. The Zn(II) atom on the inversion centre is six-coordinated by four O atoms from four different benzene-1,2,3-tricarboxyl-ate anions and two OH(-) anions. The Zn(II) atom located on a twofold axis is four coordinated by two O atoms from two different benzene-1,2,3-tricarboxyl-ate anions and two OH(-) anions. The third Zn(II) atom, located in a general position, is five coordinated by three O atoms from three different benzene-1,2,3-tricarboxyl-ate anions, one OH(-) anion and one water mol-ecule. Each benzene-1,2,3-tricarboxyl-ate anion bridges six Zn(II) atoms, and the OH(-) anion bridges three Zn(II) atoms, resulting in the formation of a three-dimensional framework. A series of O-H?O hydrogen bonds involving the benzene-1,2,3-tricarboxyl-ate anions, the OH(-) anion and the coordinating and the two water solvent mol-ecules further stablize the crystal structure. The two solvent water molecules show occupancies of 0.5 and 0.25.

Project description:The asymmetric unit of the title compound, {[Zn(2)(C(10)H(2)O(8))(H(2)O)(6)]·2H(2)O}(n), contains two distinct Zn atoms joined by a bridging water molecule and two bridging carboxyl-ate groups belonging to distinct halves of benzene-1,2,4,5-tetra-carboxyl-ate (tbec) tetra-anionic ligands, both lying on crystallographic inversion centres. The structure of this new isopolymorphic one-dimensional coordination polymer features asymmetric bimetallic octa-hedral knots. O-H?O hydrogen bonds between water molecules and carboxylate O atoms help to consolidate the crystal packing.
