Catena-Poly[[bis-(O,O'-diisopropyl dithio-phosphato-?S,S')nickel(II)]-?-bis-(4-pyridylmethyl-ene)diazane-?N:N'].

ABSTRACT: The Ni atom in the title linear supra-molecular polymer, [Ni(C(6)H(14)O(2)PS(2))(2)(C(12)H(10)N(4))](n), exists within a trans-N(2)S(4) octa-hedral donor set defined by two symmetrically coordinating dithio-phosphate ligands and pyridine N atoms derived from two bridging bis-(4-pyridylmethyl-ene)diazane ligands. The Ni atom lies on a centre of inversion and the bis-(4-pyridylmethyl-ene)diazane ligand is also disposed about a centre of inversion. The chains are arranged into layers sustained by C-H?S contacts and inter-digitate with neighbouring layers, forming the crystal structure.

catena-Poly[[[bis-(O,O'-diisobutyl dithio-phosphato-?S,S')nickel(II)]-?-1,2-bis-(4-pyridylmethyl-ene)hydrazine-?N:N'] toluene disolvate].

Project description:The polymeric title compound, {[Ni(C(8)H(18)O(2)PS(2))(2)(C(12)H(10)N(4))]·2C(7)H(7)}(n), has a linear topology and features octa-hedrally coordinated Ni atoms with a trans-N(2)S(4) donor set. The toluene solvent mol-ecules occupy channels defined by the three-dimensional stacking of the polymeric chains. The Ni atom is located at a centre of inversion and the bridging 1,2-bis-(4-pyridylmethyl-ene)hydrazine4-pyridine mol-ecule is also disposed about a centre of inversion. One isobutoxy group is disordered equally over two positions.

Project description:In the title compound, [Pb(C14H14O2PS2)2] n , the metal atom is surrounded by two O,O'-bis-(2-methyl-phen-yl) dithio-phosphate ligands bonding through the S-donor atoms. Three of the Pb-S bond lengths are are close to each other at 2.7710?(18), 2.8104?(16) and 2.8205?(16)?Å, while the fourth Pb-S bond is elongated at 3.0910?(18)?Å and reflects the fact that this atom is involved in inter-molecular bridging to an adjacent Pb(II) atom [Pb-S = 3.145?(2)?Å]. The bond angles demonstrate that the Pb(II) atom contains a stereochemically active lone pair with a distorted octa-hedral geometry about the Pb(II) atom. This distortion is shown by the S-Pb-S bite angles of 73.63?(4) and 69.50?(4)°, while the remaining S-Pb-S angles range from 81.03?(5) to 143.66?(5)°. One of the benzene rings shows positional disorder over two orientations with occupancy factors of 0.747?(11) and 0.253?(11).

Redetermination of bis-(O,O'-diethyl dithio-phosphato-?S,S')nickel(II).

Project description:The centrosymmetric title complex, [Ni{S(2)P(OC(2)H(5))(2)}(2)], has been redetermined using area-detector data. The central Ni(S(2)P)(2) core is essentially planar and confirms the early results of McConnell & Kastalsky [Acta Cryst. (1967), 22, 853-859] based on multiple film technique data. In the title structure, the standard uncertainty values are approximately seven times lower and all H-atom positions are calculated. A pair of short symmetry-related H?H contacts with distances of 2.33?Å is observed in the crystal structure.

Bis(O,O'-diphenethyl dithio-phosphato-κS,S')bis-(4-methyl-pyridine-κN)nickel(II).

Project description:The title complex, [Ni(C(16)H(18)O(2)PS(2))(2)(C(6)H(7)N)(2)], exhibits a roughly octa-hedral coordination geometry.

Important geometric data include Ni-N = 2.100 (3) Å, and Ni-S = 2.5101 (10) and 2.4772 (11) Å.

Project description:In the title compound, [Ni(C(8)F(4)O(4))(C(5)H(5)N)(2)(CH(4)O)(2)](n), the Ni(II) ion is located on an inversion center and is coordinated by four O atoms [Ni-O = 2.079?(4)?Å] from two tetra-fluoro-terephthalate ligands and two methanol mol-ecules, and by two N atoms [Ni-N = 2.127?(4)?Å] from two pyridine ligands in a distorted octa-hedral geometry.

catena-Poly[[[tetra-aqua-nickel(II)]-?-4,4'-bipyridyl-?N:N'] 3,3'-(p-phenyl-ene)diacrylate].

Project description:In the title compound, {[Ni(C(10)H(8)N(2))(H(2)O)(4)](C(12)H(8)O(4))}(n), the Ni(II), 4,4'-bipyridyl (bipy) and 3,3'-(p-phenyl-ene)diacrylate (L(2-)) moieties are situated on inversion centres.

L(2-) anions inter-act with the polymeric chains via O-H?O hydrogen bonds, forming a three-dimensional supra-molecular network.

catena-Poly[diquinolinium [[diaqua-cobaltate(II)]-?-cyclo-tetra-phosphato] hexa-hydrate].

Project description:The cyclo-tetra-phosphate anion, [P(4)O(12)](4-), forms the title complex with cobalt(II) and quinolinium, {(C(9)H(8)N)(2)[Co(P(4)O(12))(H(2)O)(2)]·6H(2)O}(n). In the complex anion, the Co(II) ion, lying on an inversion center, is surrounded by four phosphate O atoms and two water mol-ecules in a slightly distorted octa-hedral geometry. The crystal structure consists of anionic ribbons of formula {[Co(P(4)O(12))(H(2)O)(2)](2-)}(n) extending along [100]. A network of O-H?O, N-H?O and C-H?O hydrogen bonds consolidates the crystal packing.

catena-Poly[[diaqua-nickel(II)]-bis-(?-pyridine-4-sulfinato)-?N,O;?O,N].

Project description:In the title coordination polymer, [Ni(C(5)H(4)NO(2)S)(2)(H(2)O)(2)](n), the Ni(II) ion is located on an inversion centre and is octa-hedrally coordinated by two N and two O atoms of four symmetry-related and deprotonated pyridine-4-sulfinate (ps) ligands together with two water mol-ecules in axial positions. The ps(-) anions, acting as ?(2)-bridging ligands, link neighbouring Ni(II) ions into a chain structure along the c axis. These polymeric chains are extended into a three-dimensional framework via inter-molecular O-H?O hydrogen bonds with participation of the water mol-ecules.

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

Project description: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.
