Poly[[(μ2-4,4'-bipyridyl-κ(2) N:N')bis-{μ2-N-[2-(2-hy-droxy-benzo-yl)carbamo-thio-yl]acetamidato-κ(4) O,N,O':S}bis-(nitrato-κ(2) O,O')dicadmium] di-methyl-formamide tetra-solvate].

ABSTRACT: The asymmetric unit of the title complex, {[Cd2(C10H10N3O3S)2(C10H8N2)(NO3)2]·4C3H7NO} n , consists of one Cd(II) cation, one N-[2-(2-hy-droxy-benzo-yl)carbamo-thio-yl]acetamidate ligand, half a 4,4'-bipyridyl ligand, one coordinating nitrate anion and two di-methyl-formamide solvent mol-ecules of crystallization. The bipyridine ligand is completed by inversion symmetry. The metal cation exhibits a distorted penta-gonal-bipyramidal coordination geometry provided by two O and one N atoms of the thio-semicarbazide ligand, two O atoms of the nitrate anion, one S atom of a neighbouring thio-semicarbazide ligand and one 4,4'-bi-pyridine N atom. The bridging role of the thio-semicarbazide ligand through the S atom leads to centrosymmetric binuclear units, which are further linked by 4,4'-bi-pyridine units, forming polymeric chains extending along the b-axis direction. An intra-molecular N-H⋯O hydrogen bond occurs. The crystal structure also features N-H⋯O and O-H⋯O hydrogen bonds, leading to the formation of a three-dimensional network.

Poly[diaqua-bis-(nitrato-?²O,O')bis-(1,10-phenanthroline-?²N,N')-??-succinato-dicadmium].

Project description:In the title coordination polymer, [Cd?(C?H?O?)(NO?)?(C??H?N?)?(H?O)?](n), the Cd(II) ion is seven-coordinated within a distorted penta-gonal-bipyramidal O?N? environment. The succinate anions, located on an inversion centre, adopt a bis-monodentate bridging mode, leading to the formation of rods along [100]. The rods are connected by O-H?O hydrogen bonds between the coordinating water mol-ecules and nitrate O atoms of adjacent rods; the same type of hydrogen bonds are also observed between water and carboxyl-ate O atoms within the rods. ?-? stacking inter-actions with a minimum plane-to-plane separation of 3.462?(2)?Å occur between phenanthroline ligands.

?-Oxalato-bis-[(2,2'-bipyridyl)-copper(II)] bis(perchlorate) dimethyl-formamide disolvate monohydrate.

Project description:The title compound, [Cu(2)(C(2)O(4))(C(10)H(8)N(2))(4)](ClO(4))(2)·2C(3)H(7)NO·H(2)O, contains doubly charged centrosymmetric dinuclear oxalato-bridged copper(II) complex cations, perchlorate anions, and DMF and water solvate mol-ecules. In the complex cation, the oxalate ligand is coordinated in a bis-bidentate bridging mode to the Cu atoms. Each Cu atom has a distorted tetra-gonal-bipyramidal environment, being coordinated by two N atoms of the two chelating bipy ligands and two O atoms of the doubly deprotonated oxalate anion. Pairs of perchlorate anions and water mol-ecules are linked into recta-ngles by O-H?O bonds in which the perchlorate O atoms act as acceptors and the water mol-ecules as donors. Methyl groups of the DMF solvent molecule are disordered over two sites with occupancies of 0.453?(7):0.547?(7), and the water molecule is half-occupied.

Crystal structures of (2,2'-bipyridyl-κ(2) N,N')bis-[N,N-bis-(2-hydroxy-eth-yl)di-thio-carbamato-κ(2) S,S']zinc dihydrate and (2,2'-bipyridyl-κ(2) N,N')bis-[N-(2-hydroxy-eth-yl)-N-iso-propyl-dithio-carbamato-κ(2) S,S']zinc.

Project description:The common feature of the title compounds, [Zn(C5H10NO2S2)2(C10H8N2)]·2H2O, (I), and [Zn(C6H12NOS2)2(C10H8N2)], (II), is the location of the Zn(II) atoms on a twofold rotation axis. Further, each Zn(II) atom is chelated by two symmetry-equivalent and symmetrically coordinating di-thio-carbamate ligands and a 2,2'-bi-pyridine ligand. The resulting N2S4 coordination geometry is based on a highly distorted octa-hedron in each case. In the mol-ecular packing of (I), supra-molecular ladders mediated by O-H⋯O hydrogen bonding are found whereby the uprights are defined by {⋯HO(water)⋯HO(hy-droxy)⋯} n chains parallel to the a axis and with the rungs defined by 'Zn[S2CN(CH2CH2)2]2'. The water mol-ecules connect the ladders into a supra-molecular layer parallel to the ab plane via water-O-H⋯S and pyridyl-C-H⋯O(water) inter-actions, with the connections between layers being of the type pyridyl-C-H⋯S. In (II), supra-molecular layers parallel to the ab plane are sustained by hy-droxy-O-H⋯S hydrogen bonds with connections between layers being of the type pyridyl-C-H⋯S.

The formally negatively charged O atom involved in chelation also serves as a bridge. The O, O', N and S atoms comprise a square, and the Cl atom the apex of a square pyramid surrounding each metal atom. The solvate dimethyl-formamide mol-ecules, one of which is disordered over two positions in a 3:1 ratio, are hydrogen bonded to the dinuclear mol-ecule.

Bis(2,2'-bipyridyl-?N,N')(nitrato-?O,O')(trifluoro-acetato-?O)cadmium(II).

Project description:In the title complex, [Cd(C(2)F(3)O(2))(NO(3))(C(10)H(8)N(2))(2)], the Cd(II) ion is hepta-coordinated by two chelating 2,2'-bipyridyl ligands [Cd?N 2.370?(6)-2.416?(6)?Å], one carboxyl-ate O atom [Cd?O 2.290?(6)?Å] from the trifluoro-acetate ligand and two O atoms [Cd?O 2.386?(6), 2.633?(6)?Å] from a chelating nitrate anion. The trifluoro-methyl fragment is rotationally disordered between two orientations in a 0.640?(7):0.360?(7) ratio. In the crystal, weak inter-molecular C-H?O hydrogen bonds contribute to the crystal packing stability.

Bis(N-methyl-N-phenyl-carbamo-yl)disulfane.

Project description:The title compound, C(16)H(16)N(2)O(2)S(2), has been synthesized by several different high-yield routes, and has been encountered as a co-product in a number of reaction pathways, ever since it became of inter-est to our research program over 30 years ago. We now confirm the proposed mol-ecular structure in which the mol-ecule exhibits a twofold axis of symmetry through the mid-point of the S-S bond and the two planes defined by the (carbamo-yl)sulfenyl moieties are essentially perpendicular to each other [dihedral angle = 81.55?(14)°].

In the central part of the mol-ecule, the amide and thio-amide residues are approximately perpendicular [C-N-C-S torsion angle = -104.98?(18)°]. Supra-molecular layers with a zigzag topology are formed in the crystal packing by N-H?O, N-H?S and C-H?O inter-actions; these stack along c, being separated by hydro-phobic inter-actions.

Project description:The crystal structure of the title compound, [U(NO(3))(2)O(2)(C(10)H(17)Cl(3)N(3)O(2)P)(2)], is composed of centrosymmetric [UO(2)(L)(2)(NO(3))(2)] mol-ecules {L is N-[bis-(pyrrolidin-1-yl)phosphor-yl]-2,2,2-trichloro-acetamide, C(10)H(17)Cl(3)N(3)O(2)P}. The U(VI) ion, located on an inversion center, is eight-coordinated with axial oxido ligands and six equatorial oxygen atoms of the phosphoryl and nitrate groups in a slightly distorted hexa-gonal-bipyramidal geometry. One of the pyrrolidine fragments in the ligand is disordered over two conformation (occupancy ratio 0.58:0.42). Intra-molecular N-H?O hydrogen bonds between the amine and nitrate groups are found.

N,N'-Bis(phenyl-carbamo-thio-yl)benzene-1,3-dicarboxamide.

Project description:The asymmetric unit of the title compound, C22H18N4O2S2, contains two mol-ecules. In one of them, the dihedral angles between the central benzene ring and the phenyl rings are 16.97?(8) and 20.97?(8)°, while the phenyl rings make a dihedral angle of 37.87?(8)°. In the other mol-ecule, the corresponding values are 34.92?(7), 53.90?(7) and 60.68?(8)°, respectively. In each mol-ecule, two intra-molecular N-H?O hydrogen bonds generate S(6) rings and a short C-H?S contact also occurs. In the crystal, N-H?S, N-H?O, C-H?O and C-H?S inter-actions link the mol-ecules into a three-dimensional network.
