Single crystals of the title salt, (C3H10N3)2[Sn(CH3)2(H2O)4](SO4)2, formed concomitantly with the already known [Sn(CH3)3]2SO4·2H2O. In the title structure, the SnIV atom displays a slightly distorted octahedral coordination geometry defined by four O water atoms in the equatorial positions and two methyl groups in the axial positions. In the crystal, various O—H
O and N—HO hydrogen-bonding interactions between the organic cation and the coordinated water molecules as donors and the sulfate O atoms as acceptors result in a three-dimensional structure. The SnIV atom is located on an inversion centre, resulting in half of the complex metal cation being in the asymmetric unit.

The structure of the title compound, (C14H16N)2[HgCl2(SO4)], consists of an infinite chain propagating along the c direction, containing HgII ions tetracoordinated by two bridging O atoms of bis-monodentate sulfate anions and two chloride ligands. In the the crystal, N—HO hydrogen bonding between the cations and the anionic chains consolidates the packing. The crystal structure was determined from an inversion twin with approximately equal twin domains.

In the title compound, [Sn2(C4H9)4(C6H6PO3)4]n, the basic unit is a dimer containing two symmetry-related SnIV atoms bridged by two hydrogenphenylphosphonate anions. This fragment is located about an inversion center, and each SnIV atom is linked to two other hydrogenphenylphosphonate anions, giving a layered structure parallel to (010). The coordination geometry for the SnIV atoms is close to octahedral. The layers are connected via O—HO hydrogen bonds, generating a three-dimensional network. One butyl group is disordered over two sets of sites, with occupancies of 0.49 (2) and 0.51 (2).

In the title salt, [(CH3)2CH]2NH2]+·[C6H5PO2(OH)]−, the anions are linked by pairs of O—HO hydrogen bonds, forming inversion dimers. These dimers are bridged by the cations via N—HO hydrogen bonds, leading to a three-dimensional structure.
