The crystal structure of the title compound, (C6H14N)3[Sn(C2O4)2Cl2]Cl·H2O, contains three cyclo-hexyl-ammonium cations, one stannate(IV) dianion, one isolated chloride anion and one lattice water mol-ecule. The cyclo-hexyl-ammonium cations adopt chair conformations. In the complex anion, two bidentate oxalate ligands and two chloride anions in cis positions coordinate octa-hedrally to the cent...

The title compound, (C6H14N)2[Sn(C6H5)2Cl4], contains cyclo-hexyl-ammonium cations in general positions and a stannate(IV) anion that is located on a twofold rotation axis. The Sn(IV) atom in the complex anion is surrounded by four Cl(-) ligands and two trans-phenyl groups in a distorted octa-hedral configuration. The anions are connected with the cations through N-H⋯Cl hydrogen bonds. Every ca...

The Sn atom in the title substituted pyridinium stannate bromo-3,4-dichloro-benzene solvate, (C(7)H(11)N(2))(2)[SnBr(4)(C(6)H(3)Cl(2))(2)]·C(6)H(3)BrCl(2), lies on a twofold axis within an octa-hedral C(2)Br(4) donor set. Each cation forms an N-H⋯Br hydrogen bond to one of the Br atoms of the anion. The solvent mol-ecule is disordered about the twofold rotation axis with equal occupancy. The cr...

Z. Naturforsch. 38 a, 4 2 8 4 3 3 (1983); received December 28, 1982 A new matrix, 1,1,1-trifluorotrichloroethane, CF3CCI3, has been employed in radiation chemistry studies to stabilise positive ions. As a test, positive ions of benzene, toluene, orto-, metaand paraxylene and biphenyl have been generated by y-irradiation of the solutes contained in the CF3CCI3 matrix at 77 K. The ions have been...

This work investigates the influence of reaction time (ranging from 12 to 96 h) on the characteristics of zinc stannate (Zn2SnO4) nanoparticles obtained by the hydrothermal method at 200°C. The nanoparticles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), surface area measurements (BET) and infrared spectroscopy (IR). The results showed that the reaction time ...

Bis[triamminesilver(I)] bis-[diamminesilver(I)] hexa-fluorido-stannate(IV) difluoride, [Ag(NH3)3]2[Ag(NH3)2]2[SnF6]F2, was obtained in the form of colourless crystals from the reaction of CsAgSnF7 in anhydrous ammonia. Two different ammine complexes of silver(I) are present in the structure, i.e. a linear diammine and a T-shaped triammine complex. The ammine silver(I) complexes show Ag⋯Ag dista...

The reaction of the lithium tris(2-pyridyl)stannate [LiSn(2-py)3] (py6OtBu = C5H3N-6-OtBu), 1, with the element(II) amides E{N(SiMe3)2}2 (E = Sn, Pb) afforded complexes [LiE{Sn(2-py)3}3] for E = Sn (2) and E = Pb (3), which reveal three Sn–E bonds each. Compounds 2 and 3 have been characterized by solution NMR spectroscopy and X-ray crystallographic studies. Large 1J(119Sn–119/117Sn) as well as...
