Crystal structure, Hirshfeld surface analysis of 2-(eth-oxy-carbon-yl)quinolinium tetra-chlorido(quinoline-2-carboxyl-ato-κ2 N,O)stannate(IV) monohydrate.

The asymmetric unit of the title hydrated complex salt, (C12H12NO2)[Sn(C10H6NO2)Cl4]·H2O, consists of one 2-(eth-oxy-carbon-yl)quinolinium cation, one tetra-chlorido-(quinolinium-2-carboxyl-ato)stannate(IV) anion and one water mol-ecule. The compound was obtained by reaction of quinaldic acid with tin(II) chloride dihydrate in ethanol. The SnIV atom is six-coordinated by four chloride ligands and by one N and one O atom from the quinolinium-2-carboxyl-ate ligand, forming a distorted octa-hedral coordination environment. In the mol-ecular structure, intra-molecular O-H⋯O and C-H⋯Cl hydrogen bonds are observed. In the crystal, N-H⋯O, C-H⋯O and C-H⋯Cl hydrogen bonds link the components into a three-dimensional network. In addition, Y-X⋯π (Sn-Cl⋯π) and π-π stacking inter-actions involving three aromatic rings are present, with centroid-centroid separations in the range 3.633 (2)-3.864 (2) Å.
