Benzyl­triphenyl­phospho­nium dichlorido­triphenyl­stannate(IV)

The crystal structure of the title salt, (C₂₅H₂₂P)[Sn(C₆H₅)₃Cl₂] or (PhCH₂PPh₃)[SnPh₃Cl₂], consists of [PhCH₂PPh₃]⁺ cations and [SnPh₃Cl₂]⁻ anions in which the Sn^IV atom is linked to two Cl atoms and three phenyl groups in a trigonal–bipyramidal geometry, with the Cl atoms in trans positions. The cation adopts a tetra­hedral geometry. In the crystal, the cations and the anions are connected by C—H...Cl hydrogen bonds, leading to an infinite chain propagating along the c direction.

Tetra­methyl­ammonium aqua­trichlorido­oxalatostannate(IV) monohydrate

The Sn^IV atom in the title compound, [(CH₃)₄N][Sn(C₂O₄)Cl₃(H₂O)]·H₂O, obtained from the reaction between SnCl₄ and [(CH₃)₄N]₂C₂O₄·2H₂O, is six-coordinated by three Cl atoms, an O atom of a water mol­ecule and two O atoms from an asymmetrically chelating oxalate anion. The environment around the Sn^IV atom is distorted octa­hedral. The anions are connected by the lattice water mol­ecule through O—H...O hydrogen bonds, leading to a layered structure parallel to (010). The cations are located between these layers and besides Coulombic forces are connected to the anionic layers through weak C—H...O and C—H...Cl inter­actions.

Acetonyltriphenyl­phospho­nium nitrate

Crystals of the title salt, C₂₁H₂₀OP⁺·NO₃⁻, are composed of acetonyltriphenyl­phospho­nium cations and nitrate anions that mainly inter­act through electrostatic forces. The P atom in the cation has a slightly distorted tetra­hedral environment, with C—P—C angles ranging from 104.79 (7) to 112.59 (6)°. The sum of O—N—O angles of the nitrate anion is 359.99°, reflecting its trigonal–planar character. C—H...O hydrogen bonds help to consolidate the crystal packing.

Di­chlorido­diphenyl­bis­(thio­urea-κS)tin(IV)

The title compound, [Sn(C₆H₅)₂Cl₂(CH₄N₂S)₂], has been obtained from the reaction between Sn(C₆H₅)₂Cl₂ and SC(NH₂)₂. The asymmetric unit consists of one half of the mol­ecular unit, the remainder generated by a twofold rotation axis located along the Cl—Sn—Cl bonds. The Sn^IV atom is coordinated by two phenyl groups, two Cl atoms and two thio­urea ligands in an all trans octa­hedral C₂Cl₂S₂ environment. Individual mol­ecules are connected through N—H...Cl hydrogen bonds, leading to a three-dimensional network structure. Intra­molecular N—H...Cl hydrogen bonds are also present.

Tetra­butyl­ammonium butyl­tetra­chlorido­stannate(IV)

In the title compound, [N(C₄H₉)₄][Sn(C₄H₉)Cl₄], the Sn^IV atom of the stannate anion has a trigonal-bipyramidal coordination sphere by two Cl atoms and one butyl chain in the equatorial plane and by two Cl atoms in the apical positions. Two of the four butyl chains of the tetra­butyl­ammonium cation are partially disordered, each with refined site occupancies of 0.691 (6):0.309 (6). Weak C—H...Cl hydrogen-bonding inter­actions help to consolidate the crystal packing, as well as a short Cl...Cl inter­action of 3.295 (2) Å.
