2,2'-(Diselane-1,2-di-yl)dinicotinamide N,N'-dimethyl-formamide disolvate.

ABSTRACT: The asymmetric unit of the title compound, C(12)H(10)N(4)O(2)Se(2)·2C(3)H(7)NO, contains two solvent mol-ecules and two half mol-ecules of the dinicotinamide, each of which sits on a center of symmetry passing through the middle of the Se-Se bond. In each mol-ecule, the two pyridyl groups and diseleno group are approximately coplanar (r.m.s. deviations from planarity for all non-H atoms = 0.011 and 0.008?Å in the two mol-ecules). Inter-molecular N-H?O hydrogen bonds stablilize the crystal packing.

(E)-5,5'-(Diazene-1,2-di-yl)diisophthalic acid N,N-dimethyl-formamide disolvate.

Project description:The title compound, C(16)H(10)N(2)O(8)·2C(3)H(7)NO, was synthesized by the reductive condensation reaction of 5-nitro-isophthalic acid in the presence of NaOH. The tetra-acid mol-ecule, which has a crystallographically imposed centre of symmetry, adopts an E configuration with respect to the azo group. In the crystal packing, mol-ecules are linked through inter-molecular O-H⋯O and C-H⋯O hydrogen-bonding inter-actions, forming chains propagating in [20].

Project description:The title extended solid coordination compound, {[Fe(C(44)H(40)N(2)O(4)P(2))(C(3)H(7)NO)(2)](ClO(4))(2)·2C(3)H(7)NO}(n), was crystallized un-ex-pectedly from the reaction mixture containing the Trost ligand (1R,2R)-(+)-1,2-diamino-cyclo-hexane-N,N'-bis-(2'-di-phenyl-phosphinobenzo-yl) and Fe(ClO(4))(2)·6H(2)O in a 1:1 ratio in dimethyl-formamide (DMF) under reflux conditions. The polymeric complex is characterized by Fe(II) metal centers that are coordinated by two oxidized Trost ligands, each coordinated in a bidentate fashion in a square plane, along with two DMF mol-ecules above and below the plane [average Fe-O(DMF) = 2.086 (4) Å], forming an overall pseudo-octa-hedral geometry. The Trost ligand binds adjacent Fe(II) centers, each Fe(II) being bound through the O atom of one of the phosphine oxides [average Fe-O(PPh2) = 2.115 (4) Å] and the carbonyl O atom of the adjacent amide [average Fe-O(amide) = 2.192 (3) Å]. Disorder is observed in the co-solvated solvent: there are two DMF mol-ecules per Fe(II) centre, which were modeled as one DMF mol-ecule with complete occupancy and the other being modeled in two positions with equal occupancy. Disorder was also observed with one of the perchlorate anions, which was modeled in two positions with 0.75:0.25 occupancy.

4,4'-(Anthracene-9,10-di-yl)dibenzoic acid dimethyl-formamide disolvate.

Project description:In the title compound, C(28)H(18)O(4)·2C(3)H(7)NO, the dihedral angle between the benzene rings and the anthracene system is 74.05?(12)°. A crystallographic inversion centre is located in the middle of the anthracene unit. The dimethyl-formamide solvent mol-ecules are partially disordered over two positions of approximately equal occupancy [0.529?(6):0.471?(6)]. Inter-molecular O-H?O hydrogen bonds with the major occupancy formamide O atom as acceptor result in the formation of 2:1 solvate-complex aggregates, which are alternately linked to shorter solvate units via weak inter-molecular C-H?O contacts generated from the rotational disorder of the formamide O atom (minor occupancy component). Weak C-H?? inter-actions between the solvent mol-ecules as the donor and the outer anthracene rings support these contacts in the crystal structure for both disorder components.

Project description:In the title compound, C(20)H(14)N(2)O(2)·C(3)H(7)NO, the quinoxaline ring forms dihedral angles of 64.9 (2) and 30.9 (2)° with the two substituted benzene rings, which are themselves inclined at 58.4 (2)°. An intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, mol-ecules are linked through inter-molecular O-H⋯O hydrogen bonds.

Project description:The asymmetric unit of the title compound, C(14)H(8)N(2)O(8)·2C(3)H(7)NO or L·2DMF (DMF = N,N-dimethyl-formamide), contains one half of the centrosymmetric mol-ecule L and one solvent mol-ecule, which is disordered between two orientations in a 0.555?(4):0.445?(4) ratio. Inter-molecular O-H?O hydrogen bonds link one L and two DMF mol-ecules into a centrosymmetric hydrogen-bonded cluster. The crystal packing is further stabilized by weak inter-molecular C-H?O hydrogen bonds.

Bis[4-amino-N-(pyrimidin-2-yl-?N)benzene-sulfonamidato-?N](4,4'-di-methyl-2,2'-bipyridine-?N,N')cadmium dimethyl-formamide disolvate.

Project description:In the title compound, [Cd(C(10)H(9)N(4)O(2)S)(2)(C(12)H(12)N(2))]·2C(3)H(7)NO, the Cd(II) ion lies on a twofold rotation axis, is six-coordinated by N atoms, and displays a trigonal-prismatic geometry arising from the two sulfadiazinate ligands and one 4,4'-dimethyl-2,2'-bipyridine ligand. Both ligands are bidentate and coordinate via their N atoms. The O and carbonyl C atoms of the dimethyl-formamide mol-ecule show disorder and were modelled with two different orientations and with site occupancies of 0.584?(10):0.416?(10). The geometry around the sulfadiazine S atom is distorted tetra-hedral. The crystal structure involves N-H?O hydrogen bonds which link mol-ecules into a three-dimensional network. Weak C-H?O hydrogen bonds are also observed.

1,4-Bis(benzimidazol-2-yl)benzene dimethyl-formamide disolvate.

Project description:The aromatic mol-ecule of the title compound, C(20)H(14)N(4)·2C(3)H(7)NO, occupies a special position on an inversion center. The benzimidazole unit (planar to within 0.008?Å) forms a dihedral angle of 9.1?(2)° with the central benzene ring. The benzimidazole H atom participates in a hydrogen bond with the dimethyl-formamide solvent molecule, thus giving rise to the title 1:2 aggregate. These aggregates are further linked in the crystal structure by aromatic ?-? stacking inter-actions [centroid-centroid distance = 6.356?(2)?Å].

Bis{?-4'-[4-(quinolin-8-yloxymeth-yl)phen-yl]-2,2':6',2''-terpyridine}disilver(I) bis-(perchlorate) dimethyl-formamide disolvate.

Project description:In the binuclear title complex, [Ag(2)(C(31)H(22)N(4)O)(2)](ClO(4))(2)·2C(3)H(7)NO, the Ag(I) atom is penta-coordinated by three N atoms from the tridentate chelating terpyridyl group and by one N atom and one O atom from the quinolin-8-yl-oxy group in a distorted square-pyramidal geometry with the O atom at the apical position. The centrosymmetric complex cation involves intra-molecular ?-? stacking inter-actions [centroid-centroid distance = 3.862?(4)?Å] between the central pyridine and benzene rings. In the crystal structure, inter-molecular C-H?O hydrogen bonds result in the formation of a supra-molecular network.
