Crystal structure of catena-poly[[di-aqua(4,5-di-aza-fluoren-9-one-?(2) N,N')cadmium]-?-2-hydroxy-5-sulfonato-benzoato-?(3) O (1),O (1'):O (5)].

ABSTRACT: In the polymeric title compound, [Cd(C7H4O6S)(C11H6N2O)(H2O)2] n , the Cd(2+) atom is seven-coordinated by two water O atoms, by three O atoms from two 2-hy-droxy-5-sulfonato-benzoate (Hssal(2-)) ligands and by two N atoms from a 4,5-di-aza-fluoren-9-one (Dafo) ligand in a distorted penta-gonal-bipyramidal geometry. The Cd(2+) atoms are monodentately coordinated by the sulfonate group of one Hssal(2-) ligand and bidentately coordinated by the carboxyl-ate group of another Hssal(2-) ligand, generating zigzag chains running parallel to [010]. The chains are linked by O-H?O hydrogen bonds into a three-dimensional architecture.

Poly[(?(6)-2-methyl-3,5-dinitro-benzoato)potassium].

Project description:In the structure of the title coordination polymer, [K(C(8)H(5)N(2)O(6))](n), each ligand bridges six K(+) cations. The carboxyl-ate group coordinates both bidentately to one K(+) ion and monodentately to two K(+) ions, while one nitro group coordinates bidentately to a fourth K(+) ion. The last two K(+) ions are coordinated by the remaining nitro group, one in a bidentate fashion, the other monodentately through one O atom. This bridging mode results in a three-dimensional network. The coordination geometry of the K(+) ion is represented by an irregular KO(9) polyhedron. Very weak C-H?O inter-actions are observed in the crystal structure.

Crystal structure of poly[aqua-[?-1,1'-(9,9-dimethyl-9H-fluoren-2,7-di-yl)di-1H-imidazole](?-naphthalene-1,4-di-carboxyl-ato)nickel(II)].

Project description:In the title compound, [Ni(C12H6O4)(C21H18N4)(H2O)] n , the Ni(II) cation is coordinated by three carboxyl-ate O atoms of two naphthalene-1,4-di-carboxyl-ate anions, one water mol-ecule and two N atoms of two 1,1'-(9,9-dimethyl-9H-fluoren-2,7-di-yl)di-1H-imidazole (DFDI) ligands, giving rise to a slightly distorted octa-hedral geometry. The Ni(II) ions are linked by the DFDI ligands into chains, which are further connected by the carboxyl-ate anions into double chains that elongate in the the b-axis direction. These double chains are linked by centrosymmetric pairs of O-H?O hydrogen bonds into layers parallel to (10-1). The asymmetric unit consists of one crystallographically independent Ni(II) cation, one carboxyl-ate and one DFDI ligand, as well as of one water mol-ecule, all of them located in general positions.

Bis(2-{[(9H-fluoren-2-yl)methyl-idene]amino}-phenolato-?(2)N,O)zinc methanol disolvate.

Project description:In the title compound, [Zn(C(20)H(14)NO)(2)]·2CH(3)OH, the Zn(II) atom lies on a crystallographic twofold rotation axis and is coordinated by two O atoms and two N atoms from two bidentate 2-{[(9H-fluoren-2-yl)methyl-idene]amino}-phenolate ligands within a distorted tetra-hedral geometry. The dihedral angle between the two chelate rings is 82.92?(5)°. In the coordinated ligand, the phenol ring is twisted at 30.22?(9)° from the mean plane of the fluorene ring. In the crystal, O-H?O hydrogen bonds link the complex mol-ecules to the methanol solvent mol-ecules.

Triaqua-(benzene-1,3-dicarboxyl-ato)(4,5-diaza-fluoren-9-one)cadmium(II) penta-hydrate.

Project description:In the title compound, [Cd(C(8)H(4)O(4))(C(11)H(6)N(2)O)(H(2)O)(3)]·5H(2)O, the Cd(II) atom is seven-coordinated by two N atoms from one bidentate phenanthroline-derived ligand and by five O atoms, two from one bidentate benzene-1,3-dicarboxyl-ate (1,3-BDC) ligand and three from water mol-ecules, in a distorted penta-gonal-bipyramidal geometry. Neighbouring units inter-act through ?-? inter-actions [centroid-centroid distances = 3.380?(3) and 3.283?(4)?Å]. Finally, three types of O-H?O hydrogen bonds exist between coordinated dissociative water mol-ecules and hybridization water mol-ecules and carboxyl-ate O atoms, resulting in a two-dimensional network parallel to (010).

Diaqua-bis(9-oxo-4,5-diaza-fluoren-3-olato-?N,O)cadmium(II).

Project description:The title compound, [Cd(C(11)H(5)N(2)O(2))(2)(H(2)O)(2)], is a mononuclear complex consisting of a Cd(II) atom, two 3-hydr-oxy-4,5-diaza-fluoren-9-one ligands and two coordinated water mol-ecules. The Cd(II) atom, lying on a twofold axis, displays a distorted octa-hedral coordintion. Adjacent mol-ecules are linked by O-H?O hydrogen bonds and ?-? inter-actions [centroid-centroid distance = 3.84?(1)?Å], leading to a one-dimensional chain. Weak C-H?O hydrogen bonds connect the chains into a two-dimensional supra-molecular structure.

catena-Poly[[(tetra-aqua-cadmium)-?-4,4'-bipyridine-?(2)N:N'] 4-hy-droxy-3-sulfonato-benzoate monohydrate].

Project description:The two independent Cd(II) atoms in the polymeric title compound, [Cd(C(10)H(8)N(2))(H(2)O)(4)](C(7)H(4)O(6)S)·H(2)O, lie on twofold rotation axes, and each is coordinated by four water mol-ecules and the N atoms of two 4,4'-bipyridine mol-ecules in an octa-hedral geometry. Bridging gives rise to chains along [101] and [-101]. The 4-hy-droxy-3-sulfonato-benzoate dianions are not connected to the Cd(II) atoms, but form hydrogen bonds to the coordinated water mol-ecules as well as the lattice water mol-ecule, generating a three-dimensional network.

Bis(?-N-benzyl-N-furfuryldithio-carbamato)-1:2?S,S':S';2:1?S,S':S'-bis-[(N-benzyl-N-furfuryldithio-carbamato-?S,S')cadmium].

Project description:In the centrosymmetric title compound, [Cd(2)(C(13)H(12)NOS(2))(4)], pairs of dithio-carbamate ligands exhibit different structural functions. Each of the terminal ligands is bidentately coordinated to one Cd(II) atom and forms a planar four-membered CS(2)Cd chelate ring, whereas pairs of the tridentate bridging ligands link two neighbouring Cd(II) atoms, forming extended eight-membered C(2)S(4)Cd(2) tricyclic units whose geometry can be approximated by a chair conformation. The coordination polyhedron of the Cd(II) atoms is a distorted square-pyramid. The five-membered furan ring and the benzene ring are disordered over two sets of sites with an occupancy ratio of 0.62?(8):0.38?(8).

Project description:In the title complex, [Zn(C(6)H(3)N(3)O(3)S)(C(12)H(8)N(2))](n), the Zn(2+) cation is coordinated by two N atoms from two 4-sulfonato-benzotriazolide dianions, two N atoms from a 1,10-phenanthroline mol-ecule and a sulfonate O atom from a 4-sulfonato-benzotriazolide anion, displaying a distorted ZnN(4)O trigonal-bipyramidal geometry. Each 1,10-phenanthroline ligand displays a bidentate chelating coordinating mode and the 4-sulfonato-benzotriazolide ions act as ?(2)-bridges, linking different Zn(2+) cations into a chain along the b axis. The crystal structure is consolidated by C-H?O hydrogen-bonding inter-actions.
