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...
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...
In the title compound, (C(12)H(24)N)[Sn(CH(3))(3)(C(6)H(6)O(3)P)(2)], the SnMe(3) residues are axially coordinated by two monodentate [PhPO(3)H](-) anions, leading to a trigonal-bipyramidal geometry for the Sn(IV) atom. The two [SnMe(3)(PhPO(3)H)(2)](-) anions in the unit cell are associated into infinite chains along the a axis by O-H⋯O hydrogen bonds involving the hy-droxy group of the hydrog...
The title salt, (C6H14N)2[Sn(C2O4)Cl4], was obtained as a by-product from the reaction between 2C6H14N(+)·C2O4 (2-)·1.5H2O and SnCl2·2H2O. The cyclo-hexyl-ammonium cation has a chair conformation. The complex anion consists of an oxalate anion chelating the SnCl4 moiety, resulting in a distorted octa-hedral coordination sphere of the Sn(IV) atom with the O atoms in equatorial cis positions. In ...
