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

ABSTRACT: 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.

Project description:The heterometallic title complex, [Cr(2)Mn(2)(C(5)H(11)NO(2))(2)(C(5)H(12)NO(2))(2)(NCS)(4)]·4C(3)H(7)NO, was prepared using manganese powder, Reineckes salt, ammonium thio-cyanate and a non-aqueous solution of N-methyl-diethano-lamine in air. The centrosymmetric mol-ecular structure of the complex is based on a tetra-nuclear {Mn(2)Cr(2)(?-O)(6)} core. The tetra-nuclear complex mol-ecule and the two uncoordinated dimethyl-formamide mol-ecules are linked by O-H?O hydrogen bonds, while the two other mol-ecules of dimethyl-formamide do not participate in hydrogen bonding.

Crystal structure of bis-{μ-2-[bis-(2-hy-droxy-eth-yl)amino]-ethano-lato}bis-(μ-3,5-di-methyl-pyrazolato)tricopper(II) dibromide sesquihydrate.

Project description:In the title bicyclic trinuclear pyrazolate amino-alcohol complex, [Cu3(C5H7N2)2(C6H14NO3)2]Br2·1.5H2O, the central Cu atom lies on a center of symmetry and is involved in the formation of two five-membered rings. It has a coordination number of 4, is in a distorted tetra-hedral environment and is connected by the bridging oxygen atoms of the deprotonated OH groups of different amino-alcohol groups, and by the N atoms of deprotonated di-methyl-pyrazole ligands. The peripheral Cu atom is in a trigonal-bipyramidal coordination environment formed by the nitro-gen atom of the deprotonated bridging di-methyl-pyrazole unit, the bridging oxygen atom of the deprotonated OH group, two oxygen atoms of the protonated hy-droxy groups and the nitro-gen atom of tri-ethano-lamine. One of the C atoms and the Br- anion were found to be disordered over two positions with occupancy factors of 0.808 (9):0.192 (9) and 0.922 (3):0.078 (3), respectively.

Azido-{2-[bis-(2-hy-droxy-eth-yl)amino]-ethano-lato-?N,O,O',O''}cobalt(II).

Project description:In the title complex, [Co(C(6)H(14)NO(3))(N(3))] or [Co(teaH(2))N(3)], the Co(II) atom resides in a trigonal-bipymidal O(3)N(2) environment formed by three O atoms and one N atom from a simply deprotonated tetra-dentate triethano-lamine ligand, and one N atom from an azide ligand. The O atoms define the equatorial plane whereas both N atoms are in axial positions. The mononuclear units are linked through O-H?O hydrogen-bonding inter-actions between the ethanol OH groups and the ethano-late O atom of a neighbouring complex into chains running parallel to [010].

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.

cyclo-Tetra-?-oxido-tetra-kis-[(acetyl-acetonato-?O,O')bis-(ethano-lato-?O)niobium(V)].

Project description:The asymmetric unit of the title tetra-nuclear niobium(V) compound, [Nb(4)(C(2)H(5)O)(8)(C(5)H(7)O(2))(4)O(4)], contains two Nb(V) atoms, two bridging O atoms, two acetyl-acetonate and four ethano-late ligands. Each Nb(V) atom is six-coordinated by the bridging O atoms, two ethano-late and one chelating acetyl-acetonate ligands. The Nb-O distances vary between 1.817?(2) and 2.201?(2)?Å and the O-Nb-O angles vary between 78.88?(8) and 102.78?(9)°, illustrating the significant distortion from ideal ocahedral geometry. The rest of the tetra-nuclear unit is generated through an inversion centre. The C atoms of two of the ethano-late mol-ecules are disordered over two sites [occupancy ratio 0.601?(12):0.399?(12)].

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

Project description:The title compound, [Re(4)(μ(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 (μ(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.

Crystal structure of tetra-kis-(1-oxidopyridin-2-yl)methane methanol tetra-solvate.

Project description:The asymmetric unit of the title compound, C21H16N4O4·4CH3OH, consists of a quarter mol-ecule of tetra-kis-(1-oxidopyridin-2-yl)methane and one methanol solvent mol-ecule. In the crystal, the pyridine N-oxide derivative is located about a fourfold rotoinversion axis and exhibits S 4 symmetry along the c axis. An inter-molecular O-H⋯O hydrogen bond is observed between the O atom of the pyridine N-oxide and the OH group of the methanol. An inter-molecular C-H⋯O bond is also observed between adjacent pyridine N-oxide rings.

Tetra-kis(μ3-2-{[1,1-bis-(hy-droxy-meth-yl)-2-oxidoeth-yl]imino-meth-yl}-6-nitro-pheno-lato)tetra-copper(II).

Project description:The title cluster, [Cu4(C11H12N2O6)4], was obtained from the Cu(0)-FeCl2·4H2O-H4 L-Et3N-DMF reaction system (in air), where H4 L is 2-hy-droxy-methyl-2{[(2-hy-droxy-3-nitro-phen-yl)methyl-idene]amino}-propane-1,3-diol and DMF is di-methyl-formamide. The asymmetric unit consists of one Cu(2+) ion and one dianionic ligand; a -4 symmetry element generates the cluster, which contains a {Cu4O4} cubane-like core. The metal ion has an elongated square-based pyramidal CuNO4 coordination geometry with the N atom in a basal site. An intra-molecular O-H⋯O hydrogen bond is observed. The solvent mol-ecules were found to be highly disordered and their contribution to the scattering was removed with the SQUEEZE procedure in PLATON [Spek (2009 ▶). Acta Cryst. D65, 148-155], which indicated a solvent cavity of volume 3131 Å(3) containing approximately 749 electrons. These solvent molecules are not considered in the given chemical formula.

Project description:In the title compound, C(15)H(13)BrN(2)O(4)·CH(4)O, the two benzene rings form a dihedral angle of 3.2 (2)°. An intra-molecular O-H⋯N hydrogen bond is observed. In the crystal structure, mol-ecules are linked through O-H⋯O and N-H⋯O hydrogen bonds, forming a two-dimensional network parallel to (10).

Bis(4,4''-difluoro-1,1':3',1''-terphenyl-2'-carboxyl-ato-κO)tetra-kis-(methanol-κO)calcium methanol tetra-solvate.

Project description:In the title compound, [Ca(C(19)H(11)F(2)O(2))(2)(CH(3)OH)(4)]·4CH(3)OH, the Ca(2+) ion is located on an inversion centre and is hexa-coordinated by two O atoms of two 4,4''-difluoro-1,1':3',1''-terphenyl-2'-carboxyl-ate ligands and four O atoms of four methanol ligands, forming a CaO(6) polyhedron with a slightly distorted octa-hedral coordination geometry. The Ca-O-C angle between the carboxyl-ate group and the calcium ion is 171.8 (2)°. Two types of inter-molecular hydrogen-bond inter-actions (C=O⋯H and O-H⋯O) between the carboxyl-ate ligand, the methanol solvent mol-ecules and the coordinating methanol ligands generate a two-dimensional network parallel to (001).
