Crystal structure of poly[[trans-di-aqua-bis-[?2-trans-4,4'-(diazenedi-yl)dipyridine]-nickel(II)] diiodide ethanol disolvate].

ABSTRACT: In the title compound, {[Ni(C10H8N4)2(H2O)2]I2·2C2H5OH} n , the complex shows an octa-hedral environment of the Ni(2+) cation in which it is located on a centre of symmetry, linked to two water mol-ecules and the pyridine-N atoms of four 4,4'-(diazenediyl)dipyridine ligands bridging Ni(2+) cations along the b- and c-axis directions, giving rise to a two-dimensional arrangement. The Ni-N bond lengths are in the range 2.109?(4)-2.186?(3)?Å and the Ni-O bond length is 2.080?(3)?Å. The 4,4'-(diazenedi-yl)dipyridine ligand lies on an inversion centre. An O-H?O hydrogen-bond inter-action is observed between water and ethanol mol-ecules. The I(-) ions can be regarded as free anions in the crystal lattice.

Crystal structure of poly[[di-aqua-tetra-μ2-cyanido-iron(II)platinum(II)] acetone disolvate].

Project description:In the title polymeric complex, {[FePt(CN)4(H2O)2]·2C3H6O} n , the FeII cation has an octa-hedral [FeN4O2] geometry being coordinated by two water mol-ecules and four cyanide anions. The Pt cation is located on an inversion centre and has a square-planar coordination environment formed by four cyanide groups. The tetra-cyano-platinate anions bridge the FeII cations to form infinite two-dimensional layers that propagate in the bc plane. Two guest mol-ecules of acetone per FeII are located between the layers. These guest acetone mol-ecules inter-act with the coordinated water mol-ecules by O-H⋯O hydrogen bonds.

Crystal structure of poly[[μ2-di-aqua-di-aqua-μ2-l-proline-κ(2) O:O'-strontium] dibromide].

Project description:In the title coordination polymer, {[Sr(C5H9NO2)(H2O)4]Br2} n , the proline mol-ecule exists in a zwitterionic form with one of the ring C atoms disordered over two sites [site-occupancy factors = 0.57 (6):0.43 (6)]. The Sr(II) ion is nine-coordinated by six water O atoms, two monodentate and two μ2-bridging, and three carboxyl-ate O atoms of the proline ligands, with two bridging [Sr-O range = 2.524 (4)-2.800 (5) Å]. In the crystal, there is no direct inter-action between the proline mol-ecules. However, the proline and water mol-ecules associate with the bromide counter-anions through a number of inter-molecular O-H⋯Br and N-H⋯Br hydrogen-bonding inter-actions, giving a three-dimensional supra-molecular structure.

Aqua-dipyridine-bis-(N-p-tolysulfonyl-l-leucinato)nickel(II).

Project description:In each of the two mol-ecules in the asymmetric unit of the title compound, [Ni(C(13)H(18)NO(4)S)(2)(C(5)H(5)N)(2)(H(2)O)], the geometry of the Ni(2+) ion is an extremely distorted trans-NiN(2)O(4) octa-hedron, arising from its coordination by one water mol-ecule, two pyridine mol-ecules, and one O-monodentate and one O,O'-bidentate deprotonated N-p-tolysulfonyl-l-leucine ligand. In the crystal, mol-ecules are linked by N-H?O and O-H?O hydrogen bonds, forming chains along the c axis. An intra-molecular O-H?O hydrogen bond occurs in one of the mol-ecules.

Crystal structure of <i>trans</i>-di-aqua-(1,4,8,11-tetra-aza-undeca-ne)nickel(II) bis-(pyridine-2,6-di-carboxyl-ato)nickel(II).

Project description:The asymmetric unit of the title compound, trans-di-aqua-(1,4,8,11-tetra-aza-undecane-κ4 N 1,N 4,N 8,N 11)nickel(II) bis-(pyridine-2,6-di-carboxyl-ato-κ3 O 2,N,O 6)nickel(II) {[Ni(L)(H2O)2][Ni(pdc)2] where L = 1,4,8,11-tetra-aza-undecane (C7H20N4) and pdc = the dianion of pyridine-2,6-di-carb-oxy-lic acid (C7H3NO4 2-)} consists of an [Ni(L)(H2O)2]2+ complex cation and a [Ni(pdc)2]2- anion. The metal ion in the cation is coordinated by the four N atoms of the tetra-amine ligand and the mutually trans O atoms of the water mol-ecules in a tetra-gonally elongated octa-hedral geometry with the average equatorial Ni-N bond length slightly shorter than the average axial Ni-O bond [2.087 (4) versus 2.128 (4) Å]. The ligand L adopts its energetically favored conformation with five-membered and six-membered chelate rings in gauche and chair conformations, respectively. In the complex anion, the NiII ion is coordinated by the two tridentate pdc2- ligands via their carboxyl-ate and nitro-gen atom donors in a distorted octa-hedral trans-NiO4N2 geometry with nearly orthogonal orientation of the planes defining the carboxyl-ate rings and the average Ni-N bond length [1.965 (4) Å] shorter than the average Ni-O bond distance [2.113 (7) Å]. In the crystal, the NH donor groups of the tetra-amine, the carb-oxy-lic groups of the pdc2- anion and the coordinated water mol-ecules are involved in numerous N-H⋯O and O-H⋯O hydrogen bonds, leading to electroneutral sheets oriented parallel to the (001) plane.

Crystal structure of catena-poly[[[tri-aqua-strontium]-di-μ2-glycinato] dibromide].

Project description:In the title coordination polymer, {[Sr(C2H5NO2)2(H2O)3]Br2} n , the Sr(2+) ion and one of the water mol-ecules are located on twofold rotation axes. The alkaline earth ion is nine-coordinated by three water O atoms and six O atoms of the carboxyl-ate groups of four glycine ligands, two in a chelating mode and two in a monodentate mode. The glycine mol-ecule exists in a zwitterionic form and bridges the cations into chains parallel to [001]. The Br(-) counter-anions are located between the chains. Inter-molecular hydrogen bonds are formed between the amino and carboxyl-ate groups of neighbouring glycine ligands, generating a head-to-tail sequence. Adjacent head-to-tail sequences are further inter-connected by inter-molecular N-H⋯Br hydrogen-bonding inter-actions into sheets parallel to (100). O-H⋯Br and O-H⋯O hydrogen bonds involving the coordinating water mol-ecules are also present, consolidating the three-dimensional hydrogen-bonding network.

In the complex cation, the Ni(2+) atom is located on an inversion center and has an octa-hedral coordination sphere. The P-P distance in the centrosymmetric anion is 2.1853?(7)?Å. In the crystal, discrete [Ni(H2O)6](2+) cations and (H2P2O6)(2-) anions are stacked in columns parallel to the c axis and are linked into a three-dimensional network by medium-strength O-H?O hydrogen bonds.

4,4'-(Anthracene-9,10-di-yl)dibenzoic acid dimethyl-formamide disolvate.

Project description:In the title compound, C(28)H(18)O(4)·2C(3)H(7)NO, the dihedral angle between the benzene rings and the anthracene system is 74.05?(12)°. A crystallographic inversion centre is located in the middle of the anthracene unit. The dimethyl-formamide solvent mol-ecules are partially disordered over two positions of approximately equal occupancy [0.529?(6):0.471?(6)]. Inter-molecular O-H?O hydrogen bonds with the major occupancy formamide O atom as acceptor result in the formation of 2:1 solvate-complex aggregates, which are alternately linked to shorter solvate units via weak inter-molecular C-H?O contacts generated from the rotational disorder of the formamide O atom (minor occupancy component). Weak C-H?? inter-actions between the solvent mol-ecules as the donor and the outer anthracene rings support these contacts in the crystal structure for both disorder components.

Crystal structure of poly[di-aqua-(μ2-benzene-1,4-di-carboxyl-ato-κ(2) O (1):O (4))(μ2-benzene-1,4-di-carboxyl-ato-κ(4) O (1),O (1'):O (4),O (4'))bis-(μ2-3,3',5,5'-tetra-methyl-4,4'-bi-pyrazole-κ(2) N:N')dinickel(II)].

Project description:The asymmetric unit of the polymeric title compound, [Ni(C8H4O4)(C10H14N4)(H2O)] n , contains one Ni(2+) cation, one coordinating water mol-ecule, one 3,3',5,5'-tetra-methyl-4,4'-bi-pyrazole ligand and half each of two benzene-1,4-di-carboxyl-ate anions, the other halves being generated by inversion symmetry. The Ni(2+) cation exhibits an octa-hedral N2O4 coordination sphere defined by the O atoms of the water mol-ecule and two different anions and the N atoms of two symmetry-related N-heterocycles. The N-heterocycles and both anions bridge adjacent Ni(2+) cations into a three-dimensional network structure, with one of the anions in a bis-bidentate and the other in a bis-monodentate bridging mode. N-H⋯O and O-H⋯O hydrogen bonds between the N-heterocycles and water mol-ecules as donor groups and the carboxyl-ate O atoms as acceptor groups consolidate the crystal packing.
