7-Chloro-4-[(E)-N′-(4-fluoro­benzyl­idene)hydrazin­yl]quinoline monohydrate

Author(s) : de Souza, Marcus V. N. , Howie, R. Alan , Tiekink, Edward R. T. , Wardell, James L. , Wardell, Solange M. S. V.
Description : The mol­ecule of the title hydrate, C16H11ClFN3·H2O, is slightly twisted, as indicated by the dihedral angle of 9.55 (10)° formed between the quinoline ring system and the benzene ring. The conformation about the C=N double bond is E, and the amine-H atom is oriented towards the quinoline residue. ...

7-Chloro-4-[(E)-2-(2-methoxy­benzyl­idene)hydrazin-1-yl]quinoline monohydrate

Author(s) : de Souza, Marcus V. N. , Howie, R. Alan , Tiekink, Edward R. T. , Wardell, James L. , Wardell, Solange M. S. V. , Kaiser, Carlos R.
Description : In the title hydrate, C17H14ClN3O·H2O, the dihedral angle between the quinoline fused-ring system and the benzene ring is 13.4 (2)° and the conformation about the C=N bond is E. In the crystal, Nh—H⋯Ow and Ow—H⋯Nq (h = hydro­zone, w = water and q = quinoline) hydrogen bonds generate a two-dimenstion...

7-Chloro-4-[(E)-2-(4-methoxy­benzyl­idene)hydrazin-1-yl]quinoline monohydrate

Author(s) : de Lima Ferreira, Marcelle , de Souza, Marcus V. N. , Howie, R. Alan , Tiekink, Edward R. T. , Wardell, James L.
Description : The organic mol­ecule in the title hydrate, C17H14ClN3O·H2O, has a small but significant twist from planarity, as seen in the dihedral angle of 12.10 (17)° between the quinoline and benzene rings. The conformation about the C=N bond is E. Chains along the b axis are formed in the crystal structure a...

Triclinic form of bis­{di-μ-hydroxidobis[fac-aqua­tribromido­tin(IV)]} hepta­hydrate

Author(s) : de Lima, Geraldo M. , Howie, R. Alan , Tiekink, Edward R. T. , Wardell, James L. , Wardell, Solange M. S. V.
Description : The asymmetric unit of the title hydrate, 2[Sn(H2O)2(OH)2Br6]·7H2O, comprises two [Br3(H2O)Sn(μ-OH)2SnBr3(OH2)] units, but three independent mol­ecules as two of these are disposed about inversion centres, and seven water mol­ecules. In common with the monoclinic polymorph [Howie et al. (2005 ▶). In...

fac-(2-Amido­ethyl-κ2 C 1,O)trichlorido(urea-κO)tin(IV)

Author(s) : Howie, R. Alan , de Lima, Geraldo M. , Tiekink, Edward R. T. , Wardell, James L. , Wardell, Solange M. S. V.
Description : The Sn atom in the title compound, [Sn(C3H6NO)Cl3(CH4N2O)], is octa­hedrally coordinated within a CCl3NO donor set provided by a chelating amido­ethyl ligand (C and O), a urea-O atom and three facially arranged Cl atoms. Systematic variations in the Sn—Cl bond distances are correlated with the relat...
