Zinc mercury(II) tetra-kis-(seleno-cyanate).

ABSTRACT: The title crystal, [HgZn(NCSe)4] n , a coordination polymer, has a diamond-like network. In the crystal, the metal ions, Zn(2+) and Hg(2+), are both located on fourfold inversion axes and mimic the role of C atoms in the structure of diamond, and the linear seleno-cyanate bridges replace the C-C bonds. The C-N-Zn unit is almost linear and the C-Se-Hg unit is nearly a right angle. Thus, the HgZn4 (or ZnHg4) arrangement is midway between a tetra-hedron and a square plane, with two types of Hg-Zn-Hg (or Zn-Hg-Zn) angles of 92.38?(6) and 156.45?(6)°.

Tetra-kis(pyridazine-?N)bis-(seleno-cyanato-?N)cobalt(II) pyridazine disolvate.

Project description:Reaction of cobalt(II) nitrate with potassium seleno-cyanate and pyridazine leads to single crystals of the title compound, [Co(NCSe)(2)(C(4)H(4)N(2))(4)]·2C(4)H(4)N(2), which is isotypic with its nickel(II) thio-cyanate analogue. The Co(2+) cations are coordinated by two N-bonded seleno-cyanate ligands and four N atoms from four pyridazine ligands into discrete complexes. The complexes are arranged into layers parallel to (001). These layers are separated by additional non-coordinating pyridazine ligands.

Tetra-kis(pyridazine-?N)bis-(seleno-cyanato-?N)nickel(II) pyridazine disolvate.

Project description:The reaction of nickel(II) nitrate with potassium seleno-cyanate and pyridazine leads to crystals of the title compound, [Ni(NCSe)(2)(C(4)H(4)N(2))(4)]·2C(4)H(4)N(2). The Ni(II) atom is coordinated by two terminal N-bonded seleno-cyanate anions and four pyridazine ligands within a slightly distorted octa-hedral geometry. The crystal structure contains two crystallographically independent pyridazine molecules in cavities of the structure, which are not coordinated to the metal centres. The structure is pseudo-C-centered due to the positioning of the discrete coordination complexes; the non-coordinating pyridazine molecules, however, break the C-centering. In the subcell, these ligands are disordered around centres of inversion, which do not coincide with the mid-point of the mol-ecules.

Poly[tetra-kis-(seleno-cyanato-κN)bis-(methanol-κO)tris-(μ-pyrimidine-κN:N')dicobalt(II)].

Project description:In the title compound, [Co(2)(NCSe)(4)(C(4)H(4)N(2))(3)(CH(3)OH)(2)](n), the Co(II) ion is coordinated by three N-bonded pyrimidine ligands, two N-bonded seleno-cyanate anions and one O-bonded methanol mol-ecule in an octa-hedral coordination mode. The asymmetric unit consists of one Co(II) ion, one pyrimidine ligand, two seleno-cyanate anions and one methanol mol-ecule in general positions as well as one pyrimidine ligand located around a twofold rotation axis. In the crystal structure, the pyrimidine ligands bridge [Co(CNSe)(2)(CH(3)OH)] units into zigzag-like chains, which are further connected by pyrimidine ligands into layers parallel to (010).

Poly[[tetra-kis-(μ-1,2-di-4-pyridyl-ethyl-ene-κN:N')tetra-kis-(seleno-cyanato-κN)dimanganese(II)] 1,2-di-4-pyridyl-ethyl-ene disolvate].

Project description:The crystal structure of the title compound, {[Mn(NCSe)(2)(C(12)H(10)N(2))(2)]·C(12)H(10)N(2)}(2n), consists of two crystallographically independent Mn cations, four seleno-cyanate anions, four 1,2-di-pyridylethylene (bpe) ligands (two of which are located on centers of inversion) and two bpe solvent molecules. Each manganese(II) cation is coordinated by two terminally N-bonded seleno-cyanate anions and four bpe ligands within a slightly distorted octa-hedron. The manganese(II) cations are linked by the bpe ligands into chains that are further connected by these ligands into layers. These layers are stacked, forming cavities in which additional bpe solvent molecules are embedded.

[5,10,15,20-Tetra-kis(4-tol-yl)porphyrin]zinc(II) dichloro-methane solvate.

Project description:In the title complex, [Zn(C(48)H(36)N(4))]·CH(2)Cl(2), the Zn(II) atom lies on an inversion center and the dichloro-methane solvent mol-ecule is disordered around an inversion center. The tolyl substituents are twisted compared to the central aromatic ring system of the porphyrin, similar to what is seen in previously published structures of this molecule [Dastidar & Goldberg (1996 ▶). Acta Cryst. C52, 1976-1980]. The dihedral angles between the mean planes of the tolyl rings and the central ring are 66.98 (6) and 60.40 (6)°.

[5,10,15,20-Tetra-kis-(penta-fluoro-phen-yl)porphyrin-ato]zinc(II) benzene disolvate.

Project description:Single crystals of the title zinc porphyrinato complex, [Zn(C44H8F20N4)]·2C6H6, were obtained by the solvent evaporation method. The molecular complex exhibits point group symmetry with the central ZnII atom located on an inversion centre. The porphyrinato core is approximately planar, and the cation has no other ligating atoms than the four porphyrinato N atoms. π-π inter-actions between benzene solvent mol-ecules and [Zn(TFPP)] units lead to multilayer packing structures. In addition, inter-molecular C-H⋯F hydrogen bonding is observed between [Zn(TFPP)] mol-ecules.

Tetra-kis(diethyl ether)tetra-?(4)-oxido-octa-kis-(penta-fluoro-phen-yl)octa-zinc.

Project description:Mol-ecules of the title compound, [Zn(8)(C(6)F(5))(8)O(4)(C(4)H(10)O)(4)], are located on a special position of site symmetry [Formula: see text]. As a result, there is just one quarter-mol-ecule in the asymmetric unit. The title compound features a Zn(4)O(4) cube. Each Zn atom in the cube carries a pentafluorophenyl substituent. Each O atom is bonded to a further Zn atom, which is connected to a pentafluorophenyl substituent and the O atom of a diethyl ether mol-ecule. All ether C atoms are disordered over two sets of sites with a site occupation factor of 0.51?(2) for the major occupied site.

cyclo-Tetra-kis(?-naphthalene-1,8-dicarboxyl-ato)tetra-kis-[diaqua-(2,2'-bipyridine)-manganese(II)] tetra-hydrate.

Project description:In the title centrosymmetric tetra-nuclear complex, [Mn(4)(C(12)H(6)O(4))(4)(C(10)H(8)N(2))(4)(H(2)O)(8)]·4H(2)O, two independent Mn(II) ions are coordinated in a slightly disorted octa-hedral environment by two aqua ligands, two naphthalene-1,8-dicarboxyl-ate (1,8-nap) ligands and one bis-chelating 2,2'-bipyridine (2,2'-bipy) ligand. In the crystal, mol-ecules are linked by inter-molecular O-H?O hydrogen bonds into chains along [100]. These chains are further linked by weak ?-? inter-actions with centroid-centroid distances in the range of 3.609?(2)-3.758?(1)?Å, forming a three-dimensional supra-molecular network.

Tetra-kis(?-4-methyl-benzoato-?O:O')bis-[(N,N-diethyl-nicotinamide-?N)zinc(II)].

Project description:In the centrosymmetric binuclear title complex, [Zn(2)(C(8)H(7)O(2))(4)(C(10)H(14)N(2)O)(2)], the Zn atoms [Zn?Zn' = 2.9494?(3)?Å] are bridged by four 4-methyl-benzoate (PMB) anions. The four nearest O atoms around each Zn(II) ion form a distorted square-planar arrangement, the octahedral coordin-ation being completed by the pyridine N atom of the N,N-diethyl-nicotinamide (DENA) ligand. Each Zn(II) ion is displaced by 0.3530?(1)?Å from the plane of the four O atoms. The dihedral angles between carboxyl-ate groups and their adjacent benzene rings are 5.88?(10) and 11.89?(9)°, while the benzene rings are oriented at a dihedral angle of 75.19?(4)°. The pyridine ring is oriented at dihedral angles of 38.28?(4) and 49.17?(4)° with respect to the benzene rings. In the crystal structure, weak inter-molecular C-H?O hydrogen bonds link the mol-ecules into a three-dimensional network. ?-? contacts between parallel benzene rings [centroid-centroid distance = 3.8388?(8)?Å] and between parallel pyridine rings [centroid-centroid distance = 3.4855?(7)?Å] may further stabilize the crystal structure.
