Trimethyl­ammonium dichlorido­triphenyl­stannate(IV)

In the structure of the title monomeric coordination salt, (C₃H₁₀N)[Sn(C₆H₅)₃Cl₂], the Sn^IV atom is five coordinate, with the SnC₃Cl₂ entity in a trans trigonal–bipyramidal arrangement and the chlorine atoms in apical positions. In the crystal, the cations and anions are connected by N—H...Cl hydrogen bonds.

Dibutyl­ammonium bis­(hydrogen methylphosphonato-κO)triphenylstannate(IV)

The asymmetric unit of the title organotin salt, (C₈H₂₀N)[Sn(C₆H₅)₃(CH₄O₃P)₂], contains two dibutyl­ammonium cations and two stannate(IV) anions consisting each of two monodentately bonding methyl hydrogenphosphate groups attached to an Sn(C₆H₅) unit. The overall coordination environment of the two Sn^IV atoms is trigonal–bipyramidal defined by three phenyl C atoms in equatorial positions and two methyl hydrogenphosphate O atoms at the apical sites. In the crystal, the stannate(IV) anions are linked to each other via pairs of short O—H...O hydrogen bonds, leading to an infinite chain extending parallel to the b-axis direction. Neighbouring chains are linked by N—H...O hydrogen bonds involving the butyl­ammonium cations, giving a two-dimensional structure parallel to the ab plane. The crystal under investigation was found to be twinned by reticular merohedry with twin fractions of 0.5342 (7):0.4658 (7).

Poly[dibutyl­ammonium [nonamethylbis­(μ₃-sulfato-κ³O:O′:O′′)tristannate(IV)]]

In the structure of the title coordination polymer, {(C₈H₂₀N)[Sn₃(CH₃)₉(SO₄)₂]}_n, each of the three Sn^IV atoms is coordinated in a trigonal–bipyramidal manner by three methyl groups in the equatorial plane and by two O atoms of SO₄²⁻ anions in the axial positions. The μ₃-bridging mode of the sulfate anions leads to the formation of corrugated anionic layers parallel to (100). The uncoordinating O atom of one of the two SO₄²⁻ anions is N—H...O hydrogen-bonded to the dibutyl­ammonium cation inter­connecting the anionic sheets. The structure is partially disordered. The dibutyl ammonium ion is found on two positions with an occupancy ratio of 0.525 (10):0.475 (10), and one sulfate group with three connecting trimethyl stannyl groups is also positionally disordered over two sets of sites with an occupancy ratio of 0.725 (4):0.275 (4).

Dicyclo­hexyl­ammonium hydrogen phenyl­phospho­nate

In the title salt, [(C₆H₁₁)₂NH₂]⁺·[C₆H₅PO₂(OH)]⁻, the anion is monodeprotonated and acts as both a hydrogen-bond donor and acceptor. The anions are linked by pairs of O—H...O inter­actions, forming inversion dimers with R₂²(8) ring motifs. These dimers are bridged by two dicyclo­hexyl­aminium cations via pairs of N—H...O hydrogen bonds, giving R₄⁴(12) ring motifs, forming chains propagating along [010]. The chains are bridged by C—H...O inter­actions, forming a two-dimensional network lying parallel to (101).
