Tetra-?(3)-hydroxido-tetra-kis-[tricarbonyl-rhenium(I)] pyridine tetra-solvate.

ABSTRACT: The title compound, [Re(4)(?(3)-OH)(4)(CO)(12)]·4C(5)H(5)N, crystallizes with one tetranuclear rhenium(I) cubane-like molecule and four pyridine mol-ecules in the asymmetric unit. The coordination environment of each Re(I) atom is distorted octahedral. Four intra-molecular O-H?N and four inter-molecular C-H?O hydrogen-bond inter-actions are observed. Relatively strong hydrogen bonds are found between the hydrogen-bond donor (?(3)-OH) and acceptor (basic N atom of pyridine), with N?O distances between 2.586?(10) and 2.628?(10)?Å. Inter-cube distances of 9.873?(2) and 12.376?(3)?Å are observed.

Tetra-kis{μ(3)-2-[(2-hy-droxy-eth-yl)amino]-ethano-lato}tetra-kis-[chloridonickel(II)] methanol solvate.

Project description:The complex mol-ecule of the title compound, [Ni(4)(C(4)H(10)NO(2))(4)Cl(4)]·CH(3)OH, consists of a cubane-like {Ni(4)O(4)} core in which each nickel(II) atom is six-coordinated in a distorted octa-hedral geometry by one N and four O atoms of three mono-deprotonated diethano-lamine ligands and by a chloride anion. The mol-ecular conformation is stabilized by intra-molecular O-H⋯Cl bonds. In the crystal structure, complex mol-ecules and methanol solvent mol-ecules are linked into a three-dimensional network by N-H⋯Cl, N-H⋯O and O-H⋯Cl hydrogen-bonding inter-actions.

μ-2,3,5,6-Tetra-kis(pyridin-2-yl)pyrazine-bis-[(2,2':6',2''-terpyridine)-ruthenium(II)] tetra-kis-(hexa-fluoridophosphate) acetonitrile tetra-solvate.

Project description:In the title compound [Ru(2)(C(15)H(11)N(3))(2)(C(24)H(16)N(6))](PF(6))(4)·4CH(3)CN, two of the counter-ions and one of the solvent mol-ecules are disordered with occupancies for the major components between 0.57 (2) and 0.64 (1). The structure of the dinuclear tetracation exhibits significant distortion from planarity in the bridging 2,3,5,6-tetra-kis-(pyridin-2-yl)pyrazine (tppz) ligand, which has a saddle-like geometry with an average dihedral angle of 42.96 (18)° between adjacent pyridine rings. The metal-ligand coordination environment is nearly equivalent for the two Ru(II) atoms, which have a distorted octa-hedral geometry due to the restricted bite angle [157.57 (13)-159.28 (12)°] of their two mer-arranged tridendate ligands [2,2':6',2''-terpyridine (tpy) and tppz] orthogonal to each other. At the peripheral tpy ligands, the average Ru-N bond distance is 2.072 (4) Å for the outer N atoms trans to each other (N(outer)) and 1.984 (1) Å for the central N atoms (N(central)). At the bridging tppz ligand, the average metal-ligand distances are significantly shorter [2.058 (4) Å for Ru-N(outer) and 1.965 (1) Å for Ru-N(central)] as a result of both the geometric constraints and the stronger π-acceptor ability of the pyrazine-centered bridge. The dihedral angle between the two tpy planes is 27.11 (6)°. The intra-molecular linear distance between the two Ru atoms is 6.6102 (7) Å.

Poly[[tetra-kis-(μ-2-anilinobenzoato-κO:O')tetra-μ(1,1,1)-azido-tetra-μ(1,1)-azido-octa-methano-lhexa-nickel(II)] methanol hexa-solvate].

Project description:The crystal structure of the title compound, [Ni(6)(C(13)H(10)NO(2))(4)(N(3))(8)(CH(3)OH)(8)]·6CH(3)OH, consists of a centrosymmetric hexa-nuclear [Ni(II) (6)(C(13)H(10)NO(2))(4)(N(3))(8)(CH(3)OH)(8)] mol-ecule and six methanol solvent mol-ecules. In the hexa-nuclear unit, the six octa-hedrally coordinated Ni(II) atoms are linked by four μ(1,1,1)-azide and four μ(1,1)-azide bridges, forming a face-sharing Ni(6)N(8) tetra-cubane-like unit with four missing corners. The Ni(II) atoms are further bridged by four μ(1,2)-carboxalate groups. Neighbouring hexa-nuclear units are connected via N-H⋯O hydrogen-bonding inter-actions into a three-dimensional structure. Although the H atoms of the methanol OH groups could not be located, O⋯N/O contacts between 2.65 and 2.86 Å suggest that these mol-ecules participate in hydrogen bonding.

The asymmetric unit contains two anionic L ligands. One bridges two Er(III) cations and one Co(II) cation through two carboxyl-ate groups and one pyridine N atom, while the other bridges two Er(III) cations and one Co(II) cation through two carboxyl-ate groups. Extensive O-H⋯O, O-H⋯N and N-H⋯O hydrogen-bonding inter-actions are present in the crystal, involving all uncoordinated water mol-ecules and the uncoordinated pyridine N atom of one of the ligands bonded to an adjacent coordinated water mol-ecule. The title compound is isotypic with the gadolinium analogue.

Poly[[tetra-aqua-tetra-kis-[μ(3)-5-(pyridine-4-carboxamido)-isophthalato]-cobalt(II)-diholmium(III)] tetra-hydrate].

Project description:In the centrosymmetric polymeric title compound, {[CoHo(2)(C(14)H(8)N(2)O(5))(4)(H(2)O)(4)]·4H(2)O}(n), the Ho(III) ion is coordinated by one water mol-ecule and four 5-(pyridine-4-carboxamido)-isophthalate (L) ligands in a distorted square-anti-prismatic arrangement. The Co(II) ion, located on an inversion center, is coordinated by two pyridine N atoms, two carboxyl-ate O atoms and two water mol-ecules in a distorted octa-hedral geometry. One L ligand bridges two Ho ions and one Co ion through two carboxyl-ate groups and one pyridine N atom. The other L ligand bridges two Ho ions and one Co ion through two carboxyl-ate groups, while the uncoordinated pyridine N atom accepts a hydrogen bond from an adjacent coordinated water mol-ecule. Extensive O-H⋯O, N-H⋯O and O-H⋯N hydrogen bonding is present in the crystal.

Crystal structure of an unknown tetra-hydro-furan solvate of tetra-kis-(μ 3-cyanato-κ(3) N:N:N)tetra-kis-[(triphenyl-phosphane-κP)-silver(I)].

Project description:In the title compound, [{[(C6H5)3P]Ag}4{NCO}4], a distorted Ag4N4-heterocubane core is set up by four Ag(I) ions being coordinated by the N atoms of the cyanato anions in a μ 3-bridging mode. In addition, a tri-phenyl-phosphine ligand is datively bonded to each of the Ag(I) ions. Intra-molecular Ag⋯Ag distances as short as 3.133 (9) Å suggest the presence of argentophilic (d (10)⋯d (10)) inter-actions. Five moderate-to-weak C-H⋯O hydrogen-bonding inter-actions are observed in the crystal structure, spanning a three-dimensional network. A region of electron density was treated with the SQUEEZE procedure in PLATON [Spek (2015). Acta Cryst. C71, 9-18] following unsuccessful attempts to model it as being part of disordered tetra-hydro-furan solvent mol-ecules. The given chemical formula and other crystal data do not take into account these solvent mol-ecules.

Tetra-kis(2,2'-bipyrid-yl)dichlorido-di-?(3)-hydroxido-di-?(2)-hydroxido-tetra-copper(II) dinitrate hexa-hydrate.

Project description:The tetra-nuclear copper(II) title complex, [Cu(4)Cl(2)(OH)(4)(C(10)H(8)N(2))(4)](NO(3))(2)·6H(2)O, has a crystallographically imposed centre of symmetry. The metal atoms display a distorted tetragonal-pyramidal coordination geometry, and are linked by two ?(2)- and two ?(3)-hydroxo groups, assuming a chair-like conformation for the Cu(4)O(2) core. In the crystal, the complex mol-ecules are linked into a three-dimensional network by inter-molecular O-H?O, O-H?Cl, C-H?O and C-H?Cl hydrogen bonds and ?-? stacking inter-actions with centroid-centroid separations of 3.724?(2) and 3.767?(3)?Å.

Redetermination of cyclo-tetra-kis-(μ-5,10,15,20-tetra-4-pyridyl-porphyrinato)tetra-zinc(II) dimethyl-formamide octa-solvate trihydrate at 100 K.

Project description:The structure of the title compound, [Zn(4)(C(40)H(24)N(8))(4)]·8C(3)H(7)NO·3H(2)O, has been redetermined at 100 K. The redetermination is of significantly higher precision and gives further insight into the disorder of pyridyl groups and solvent mol-ecules. The mol-ecules of (5,10,15,20-tetra-4-pyridyl-porphyrinato)zinc(II) (ZnTPyP) form homomolecular cyclic tetra-mers by coordination of a peripheral pyridyl group to the central Zn atom of an adjacent symmetry-related mol-ecule. The tetra-mer so formed exhibits mol-ecular S(4) symmetry and is located about a crystallographic fourfold rotoinversion axis. Severely disordered dimethyl-formamide and water mol-ecules are present in the crystal, the contributions of which were omitted from refinement. Inter-molecular C-H⋯N hydrogen bonding is observed.
