In the title solvated salt, (C10H10NO)[SnCl4(C9H6NO)]·CH3CN, the SnIV atom is chelated by the N,O-bidentate 8-hydroxy­quinolinate ligand and four chloride ions, generating a distorted SnONCl4 octa­hedral coordination geometry for the metal. In the crystal, the cations are linked to the anions and the solvent mol­ecules by O—H⋯O and N—H⋯N hydrogen bonds, respectively.

In the title salt, (C11H10NO2)[SnCl4(C10H6NO2)]·CH3OH, the Sn atom is chelated by the quinolincarboxyl­ate unit and it exists in a distorted octa­hedral coordination geometry. The cation is linked to the solvent mol­ecule by an N—H⋯O hydrogen bond; the solvent mol­ecule is linked to the anion by an O—H⋯O hydrogen bond.

The asymmetric unit of the title cocrystal, [Sn(CH3)(C6H5)Cl2(H2O)2]·C10H20O5, contains two independent for­mula units. The organotin molecules exhibit a six-coordinate metal atom and are linked to the crown ether molecules by water–crown ether O—H⋯O hydrogen bonds into a linear chain running along [101]. Each coordinated water mol­ecule forms a pair of hydrogen bonds to the same crown ether; for the crown ether mol­ecules, only four of the five O atoms are engaged in hydrogen-bonding inter­actions. The metal ions show a distorted trans-C2SnCl2O2 octa­hedral coordination geometry [C—Sn—C = 175.3 (1) and 178.9 (1)°].

In the crystal, the cation and anion are linked to the methanol molecules by O-HÁ Á ÁO and N-HÁ Á ÁO hydrogen bonds. Related literature
