Catena-Poly[[[di-?(2)-hydroxido-bis-[(di-2-pyridylamine)nickel(II)]]-?-fumarato] dihydrate].

ABSTRACT: The Ni(II) ion in the one-dimensional title complex, {[Ni(2)(C(4)H(2)O(4))(OH)(2)(C(10)H(9)N(3))(2)]·2H(2)O}(n), has a distorted square-pyramidal coordination environment formed by three O atoms from two bridging hydroxide groups and one carboxyl-ate group of the fumarate ligand and two pyridine N atoms from a di-2-pyridylamine (dpa) ligand. Two hydroxide groups link adjacent metal centers, forming a centrosymmetric four-membered [Ni(2)(OH)(2)] ring. In the crystal structure, the H atoms of the bridging hydroxide groups form inter-molecular hydrogen bonds to both water mol-ecules. These are further linked to the uncoordinated O atoms of the carboxyl-ate groups and the NH group of a dpa ligand to generate a three-dimensional network from the chains of the coordination polymer.

Project description:In the crystal structure of the title compound, {[Ni(C(4)H(2)O(4))(C(10)H(9)N(3))(H(2)O)(2)]·4H(2)O}(n), zigzag chains are built up from cis-[Ni(dpya)(H(2)O)(2)](2+) cations (dpya is di-2-pyridylamine) linked by bis-monodentate coordinated bridging fumarate ligands. The Ni(II) atom is coordinated by one chelating dpya ligand, two aqua ligands in trans positions and two monodentate fumarate ligands in cis positions in the form of a deformed octa-hedron. The water mol-ecules, O atoms of the fumarate carboxyl-ate groups and the amine group of the dpya ligand are involved in an extended network of intra- and inter-molecular O-H?O hydrogen bonds. Moreover, ?-? inter-actions between the pyridine rings of the dpya ligand contribute to the stability of the structure. Two of the five uncoordinated water molecules are half-occupied.

catena-Poly[[gallium(III)-bis-[?-D/l-tartrato(2-)]-gallium(III)-di-?-hydroxido] dihydrate].

Project description:In the title compound, {[Ga(2)(C(4)H(4)O(6))(2)(OH)(2)]·2H(2)O}(n), the Ga(III) atom is located on a twofold rotation axis and is six-coordinated by two O atoms from bridging hydroxide groups and four O atoms from two symmetry-related tartrate units in a slightly distorted octa-hedral environment. Each tartrate unit binds to two Ga(III) atoms as a bis-chelating bridging ligand by two pairs of hydroxide groups and an O atom of a carboxyl-ate group. The Ga(III) atoms are linked by two bridging hydroxide groups located on mirror planes. In this way a chain along the c axis is formed. Free water mol-ecules on mirror planes are located between the chains and hold them together through hydrogen-bonding inter-actions, with O?O distances in the range 2.509?(3)-3.179?(5)?Å.

catena-Poly[[diazido-zinc(II)]-?-di-4-pyridylamine-?N:N'].

Project description:In the title compound, [Zn(N(3))(2)(C(10)H(9)N(3))](n), tetra-hedrally coordinated Zn(II) ions with two monodentate azide ligands are linked into zigzag one-dimensional chain motifs by di-4-pyridylamine (dpa) tethers. Individual [Zn(N(3))(2)(dpa)](n) chains are connected into supra-molecular layers via N-H?N hydrogen bonding between the central amine groups of the dpa ligands and terminal unligated azide N atoms. The azide ligands in one supra-molecular layer penetrate through the neighboring layers above and below, allowing stacking into a three-dimensional structure.

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.

catena-Poly[[aqua-dipyridine-copper(II)]-μ-fumarato].

Project description:The title compound, [Cu(C(4)H(2)O(4))(C(5)H(5)N)(2)(H(2)O)](n), is a one-dimensional coordination polymer based on pyridine and fumarate ligands. Each Cu(II) cation is coordinated by two carboxyl-ate O atoms belonging to two fumarate anions, two N atoms from two pyridine mol-ecules and one water mol-ecule, in a square-based pyramidal geometry.

Neighbouring chains are linked together to form a two-dimensional network parallel to the ac plane via hydrogen bonding inter-actions between uncoordinated carboxyl-ate O atoms and coordinated water mol-ecules of adjecent chains.
