The title quaternary compound, dibarium tetra-anti-mony germanium deca-sulfide, Ba2Sb4GeS10, crystallizes in a novel three-dimensional ∞ (3)[Sb4GeS10](4-) network structure, which is composed of triangular pyramidal SbS3 (site symmetry m..), distorted SbS5 (m..) polyhedra and regular GeS4 (-4..) tetra-hedra. The SbS3 and SbS5 units are connected with each other through corner- and edge-sharing,...
Crystallization from an aqueous methanol system composed of Ni(NO3)2, 2,2'-bipyridine (bpy) and LiTCNQ (TCNQ is 7,7,8,8-tetra-cyano-quinodi-methane) in a 1:3:2 molar ratio yielded single crystals of bis-[tris-(2,2'-bi-pyridine-κ2N,N')nickel(II)] bis-(7,7,8,8-tetra-cyano-quinodi-methane radical anion) bi[7,7,8,8-tetra-cyano-quino-dimethanide] hexa-hydrate, [Ni(C10H8N2)3]2(C24H8N8)(C12H4N4)2·6H2O...
In the title compound, C(10)H(9)Cl(2)NO(3)S, the S atom, which is a component atom of a heterocyclic ring, shows tetra-hedral coordination. The heterocyclic ring is not planar.
In the title complex, [Mn(C(22)H(18)N(2)O(4))Cl], the Mn(III) centre is in a distorted square-pyramidal configuration, with the basal plane formed by the N(2)O(2) donors of the tetra-dentate Schiff base dianion; the two phenolate O atoms and the two imine N atoms are each mutually cis. The chloride ion occupies the apical position. The dihedral angle between the two outer phenolate rings of the...
In the title compound, C(16)H(13)IN(2), the benzene ring of the tetra-hydro-isoquinoline moiety makes a dihedral angle of 45.02 (9)° with the benzene ring of the 4-iodo-phenyl fragment. The N atom and the adjacent unsubstituted C atom of the tetra-hydro-isoquinoline unit are displaced by 0.294 (2) and 0.441 (3) Å, respectively, from the plane through the remaining eight C atoms. In the crystal,...
In the title compound, C(33)H(34)N(6)O(6), the dihydro-benzimidazol-2-one ring system is essentially planar (r.m.s. deviation = 0.021 Å). The cyclo-hexane ring adopts a chair conformation. In the 5-(biphenyl-2-yl)-2H-tetra-zole fragment, the tetra-zole ring is twisted away from the attached benzene ring by 35.73 (11)° and the two benzene rings form a dihedral angle of 68.00 (9)°. An intra-molec...
THE ASYMMETRIC UNIT OF THE TITLE COMPOUND [SYSTEMATIC NAME: benzamidinium 3,3',5,5'-tetra-hydr-oxy-1,1'-spirobi[2,4,6-trioxa-1,3,5-triboracyclo-hexa-ne](1-) sesquihydrate], C(7)H(9)N(2) (+)·B(5)H(4)O(10) (-)·1.5H(2)O, is composed of two protonated benzamidinium cations, two tetra-hydro-penta-borate anions and three water mol-ecules of crystallization. The ions and water molecules are associated...
The zwitterionic title compound, C(13)H(8)F(2)N(4)S, is situated on a twofold rotation axis running along the C-S [1.691 (2) Å] single bond. The phenyl-ene ring is twisted out of the tetra-zolium plane by 42.18 (7)°. Relatively short distances [3.7572 (9) and 4.0625 (6) Å] between the centroids of the phenyl-ene and tetra-zolium rings of neighbouring mol-ecules suggest π-π inter-actions. The cr...
The crystal of the title compound, C(9)H(20)N(+)·C(9)H(21)O(3)SSi(-), is built of aggregates, each made up of two 2,2,6,6-tetra-methyl-piperidinium cations and two triisopropoxysilanethiol-ate anions. The aggregates are linked by four N-H⋯S bonds and correspond to an R(2) (4)(8) graph-set motif.
In the title mol-ecule, C(27)H(26)Cl(2)N(2)O(2), the chloro-substituted benzene rings make dihedral angles of 83.29 (9) and 80.81 (9)° with the benzene ring of the tetra-hydro-quinoline group. The dihedral angle formed by the two chloro-substituted benzene rings is 40.87 (12)°. The six-membered N-containing ring is in a half-chair conformation. In the crystal structure, inter-molecular N-H⋯O hy...
