Poly[di-?(5)-adipato-?O:O':O'':O''',O'''-?(4)-adipato-?O:O':O'':O'''-bis-[2-phenyl-1H-1,3,7,8-tetra-azacyclo-penta-[l]phenanthrene-?N,N]tricobalt(II)].

ABSTRACT: In the title polymer, [Co(3)(C(6)H(8)O(4))(3)(C(19)H(12)N(4))(2)](n), two adipate dianions (C(6)H(8)O(4) (2-)) occupy general positions and two are situated on different inversion centres. The two on general positions bind through their four O atoms to five 2-phenyl-1H-1,3,7,8-tetra-azacyclo-penta-[l]phenanthrene-chelated Co(II) ions, whereas the two on special positions bind to only four. Of the three Co atoms, two are chelated by N-heterocycles; the third is bonded to six O atoms. The bonding mode of the dianion gives rise to a three-dimensional network structure; the network is further consolidated by N-H?O hydrogen bonds.

Project description:The carboxyl-ate dianion in the title compound, [Pb(C(14)H(8)O(5))(C(19)H(12)N(4)O)(2)]·2H(2)O, uses one carboxyl-ate group to O,O'-chelate a bis-[4-(1H-1,3,7,8-tetra-azacyclo-penta-[l]phen-anthren-2-yl)phenol]-chelated Pb(II) atom and uses its other carboxyl-ate group to bind to another Pb(II) atom in an irregular monodentate manner. The Pb(II) atom exists in an undefined seven-coordinate geometry in the chain structure; the lone pair is stereochemically active. Adjacent chains are linked by inter-molecular O-H⋯N, N-H⋯O and O-H⋯O hydrogen bonds that involve the uncoordinated water mol-ecules to form a three-dimensional network.

Project description:The 1,4-dicarboxyl-ate dianions in the title compound, [Mn(C(12)H(6)O(4))(C(19)H(12)N(4)O)(2)]·0.5C(12)H(8)O(4)·H(2)O, bond to two 4-(1H-1,3,7,8-tetra-azacyclo-penta-[l]phenanthren-2-yl)phenol-chelated Mn atoms to form a chain that features the metal atom in an octa-hedral coordination geometry. Adjacent chains inter-act with the uncoordinated water mol-ecules to form a three-dimensional network. The naphthalene-1,4-dicarboxylic acid solvent mol-ecule, which is disordered about a centre of inversion, occupies the space within the network but is not bonded to the network. One NH group is disordered equally over two positions.

catena-Poly[[tetra-kis-(μ-penta-fluoro-benzoato-κO:O')dimolybdenum(II)]-μ-4,4'-bipyridine-κN:N'].

Project description:In the title compound, [Mo(2)(C(7)F(5)O(2))(4)(C(10)H(8)N(2))](n), the mol-ecule forms a paddle-wheel-type structure. Each Mo(2) (4+) unit is equatorially coordinated by four pentafluoro-benzoate groups, while the axial positions are occupied by two 4,4'-bipyridine mol-ecules. The Mo-Mo bond length of 2.1227 (4) Å is representative of a dimolybdenum quadruple bond. An infinite linear chain parallel to [110] is formed by the Mo(2) (4+) unit coordinating axially to the two N atoms of the 4,4'-bipyridine ligand [Mo-N = 2.594 (2) Å]. The crystal packing shows mol-ecules linked together into a three-dimensional network via Mo-N coordination inter-actions and weak π-π stacking inter-actions between perfluoro-phenyl rings [centroid-centroid distance = 3.7280 (3) Å and centroid-to-plane distance = 3.6103 (12) Å between two penta-fluoro-phenyl rings].

Bis(?-3,5-dinitro-2-oxidobenzoato)-?O,O:O;?O:O,O-bis[aqua-(2-phenyl-1,3,7,8-tetra-azacyclo-penta-[l]phenanthrene-?N,N)cobalt(II)].

Project description:In the title compound, [Co(2)(C(7)H(2)N(2)O(7))(2)(C(19)H(12)N(4))(2)(H(2)O)(2)], the Co(II) atom is six-coordinated by two N atoms from a 2-phenyl-1H-1,3,7,8,-tetraaza-cyclo-penta-[l]phenanthrene (L) ligand, three O atoms from two 3,5-dinitro-2-oxidobenzoate (3,5-dinitro-salicylate or DNSA) ligands and one O atom from a water mol-ecule in a distorted octa-hedral geometry. The Co(II) atoms are bridged by two carboxyl-ate O atoms from two DNSA ligands, forming a centrosymmetric dinuclear structure. Neighbouring dinuclear units inter-act with each other through two types of ?-? inter-actions between the L ligands [shortest centroid-centroid distance = 3.646?(3)?Å] and between the L and DNSA ligands [shortest atom-to-centroid distance = 3.794?(3)?Å]. N-H?O, O-H?N and O-H?O hydrogen bonds are observed, which lead to a three-dimensional structure.

Project description:One of the two 1,4-dicarboxyl-ate dianions in the title compound, [Mn(2)(C(12)H(6)O(4))(2)(C(19)H(12)N(4))(2)]·C(3)H(7)NO, uses its two carboxyl-ate groups to chelate two N-heterocycle-chelated Mn atoms; the other 1,4-dicarboxyl-ate dianion binds to four such metal centers. The octa-hedrally coordinated Mn atoms are linked through the two dianions into a layer motif; the dimethyl-formamide mol-ecules occupy the spaces between adjacent layers. Ten C atoms and attached H atoms of one dianion are disordered equally over two positions.

Tetra-kis(μ-penta-fluoro-benzoato-κO:O')bis-[(tetra-hydro-furan-κO)molybdenum(II)].

Project description:In the asymmetric unit of the title compound, [Mo(2)(C(7)F(5)O(2))(4)(C(4)H(8)O)(2)], two independent half-mol-ecules are present, which are completed by a crystallographically imposed center of inversion between the individual Mo atoms. In each mol-ecule, four penta-fluoro-benzoate anions bridge the quadruply bonded Mo(2) (4+) unit that is, in addition, axially coordinated by two O atoms of tetra-hydro-furan (THF) mol-ecules. In the two independent mol-ecules, the mean Mo-Mo bond length is 2.110 Å. Since the THF mol-ecules are equally disordered over two sets of sites, there are four different Mo-O distances in both half-mol-ecules with an overall mean of 2.542 Å. A zigzag chain is formed by π-π stacking inter-actions between penta-fluoro-phenyl rings, indicated by a centroid-centroid distance of 3.7054 (11) Å and a centroid-to-plane distance of 3.4169 (3) Å. The extension of the unit gives a three-dimensional network structure with the THF mol-ecules located in the voids.

The structure also contains an uncoordinated 5,5'-dimethyl-2,2'-bipyridine molecule with an N-C-C-N torsion angle of 169.5 (7)°. The triply bridged Yb centers are 3.5990 (4) Å apart.

μ-2,3,5,6-Tetra-2-pyridylpyrazine-κN,N,N:κN,N,N-bis-[(methanol-κO)(nitrato-κO,O')(nitrato-κO)cadmium(II)].

Project description:The title complex, [Cd(2)(NO(3))(4)(C(24)H(16)N(6))(CH(4)O)(2)], displays a centrosymmetric dinuclear structure, in which the 2,3,5,6-tetra-2-pyridinylpyrazine (tppz) ligand links two Cd ions separated by 7.323 (4) Å. Each Cd(II) center is seven-coordinated by three N-atom donors of tppz in one plane, by two O atoms nearly normal to this plane, and by two O atoms 0.393 (3) and 0.488 (3) Å from that plane. The two Cd(II) ions are above and below the plane of the pyrazine ring of the tppz ligand, oriented with respect to the pyridine rings at dihedral angles of 38.01 (3) and 31.90 (3)°. The dihedral angle between the two pyridine rings is 41.11 (3)°. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules.
