Catena-Poly[[[bis-[4-(1H-1,3,7,8-tetra-azacyclo-penta-[l]phenanthren-2-yl)-phenol-κN,N]lead(II)]-μ-4,4'-oxy-dibenzoato-κO,O':O''] dihydrate].

ABSTRACT: 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[[diaqua-cadmium(II)]-μ-4,4'-sulfonyl-dibenzoato-κO:O].

Project description:The title compound, [Cd(C(14)H(8)O(6)S)(H(2)O)(2)](n), comprises zigzag chains parallel to [111] of alternating [Cd(H(2)O)(2)](2+) and sulfonyl-dibenzoate units, with the Cd and S atoms lying on crystallographic twofold axes. The central Cd(II) ion is in a slightly distorted octa-hedral geometry, coordinated by six O atoms from two carboxyl-ate groups and two water O atoms. An intra-molecular C-H⋯O hydrogen bond occurs. In the crystal, inter-molecular hydrogen bonds between carboxyl-ate O atoms and coordinated water mol-ecules in adjacent chains lead to the formation of a three-dimensional network structure. The compound is isotypic with the Zn analog.

2-Phenyl-1H-1,3,7,8-tetra-azacyclo-penta-[l]phenanthrene.

Project description:There are two molecules in the asymmetric unit of the title compound, C(19)H(12)N(4). One is almost planar [dihedral angle between the fused-ring system and the phenyl ring = 2.16 (13)°] and one is somewhat twisted [dihedral angle = 13.30 (14)°]. In the crystal, the molecules are linked by N-H⋯N hydrogen bonds to result in chains.

Project description:In the title complex, [Zn(C(15)H(10)O(6))(H(2)O)(2)](n), the Zn(II) atom is located on a twofold rotation axis and exhibits a distorted tetrahedral coordination environment defined by two O atoms from two 4,4'-(methyl-enedioxy)-dibenzoate ligands and two O atoms from two coordinated water mol-ecules. In the crystal structure, mol-ecules are linked into a three-dimensional framework by O-H?O hydrogen bonds and C-H?? inter-actions.

Bis(μ-3,5-dinitro-2-oxidobenzoato)-κO,O:O;κO:O,O-bis[aqua-(2-phenyl-1,3,7,8-tetra-azacyclo-penta-[l]phenanthrene-κN,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 π-π 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.

catena-Poly[[(2,2'-bipyridine)-manganese(II)]-μ(3)-4,4'-sulfonyl-dibenzoato].

Project description:In the title compound, [Mn(C(14)H(8)O(6)S)(C(10)H(8)N(2))](n), the Mn(II) ion is coordinated by four O atoms from three 4,4'-sulfonyl-dibenzoate (sdba) ligands and two N atoms from one 2,2'-bipyridine (2,2'-bipy) ligand in a distorted octa-hedral geometry. The manganese atoms are alternately bridged either by two sdba ligands, with an Mn⋯Mn separation of 12.284 (1) Å, or by two carboxyl-ate groups from two sdba ligands, with an Mn⋯Mn separation of 4.064 (1) Å, thus producing polymeric chains propagated in [101]. Weak inter-molecular C-H⋯O hydrogen bonds and π-π inter-actions [centroid-centroid distance of 3.730 (3) Å between the aromatic rings of neighbouring polymeric chains] further stabilize the crystal packing.

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

Project description: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.

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].

catena-Poly[[[diaqua-copper(II)]-{?-4,4'-[1,4-phenyl-enebis(methyl-eneimino)]dibenzoato}] monohydrate].

Project description:The asymmetric unit of the title polymeric compound, {[Cu(C(22)H(18)N(2)O(4))(H(2)O)(2)]·H(2)O}(n), contains a Cu ion situated on an inversion center, half of a centrosymmetric 4,4'-[1,4-phenyl-enebis(methyl-eneimino)]dibenzoate ligand, a coordin-ated water mol-ecule in a general position and an uncoordin-ated water mol-ecule situated on a twofold rotation axis. The distorted octa-hedral coordination geometry of the Cu(II) ion is formed by six O atoms. The -NH- groups of the ligand are involved in intra-molecular N-H?O hydrogen bonds, while the water mol-ecules participate in the formation of a three-dimensional supra-molecular framework via inter-molecular O-H?O hydrogen bonds.
