Tin(IV) Halides Zero-dimensional based Inorganic-Organic Hybrid Materials: Crystal Structures and Hirshfeld Surface Analysis

Two tetramethylguanidinium halostannate inorganic-organic hybrid compounds was isolated and structurally investigated by single crystal X-ray crystallography Hirshfeld surface analysis. The compound [(C6H14N3)2SnCl6] (1), crystallizes in the orthorhombic space group Fddd with Z = 8 / Z’ 0.25, a 7.3474(3) Å, b 22.3678(8) c 28.4908(10) Å V 4682.3(3) Å3. [(C6H14N3)2SnBr6] (2), 7.5767(5) 23.0591(17) 29.008(2) 5068.0(6) isolation of 1 undergoes redox process from Sn(II) to Sn(IV) solution non-controlled atmosphere. Both 2 describe TMG+ ions central carbon atom trigonal–planar fashion. With respect this CN3 plane, pairs di­methyl­ammonium groups are twisted 13.70 (8) 32.21 (8)° for 1, 14.88 (13) 31.95(13)° 2. SnX6 dianions evidence slightly distorted octahedron (Oh) about Sn centre hybrids Within structures materials 2, N-H···Cl inter-species hydrogen bonding patterns between inorganic stannate organic entities give rise one-dimensional chain, wherein species alternate. propagation chain generates rings. weak C-H···X bonds formed methyl adjacent tetramethylguanidinium-stannate chains result supramolecular three-dimensional hydrogen-bonded network. analysis shows existence both strong interactions. Inspection analysis, show isostructural behavior. Hybrids first reports tetra- or hexa-halostannate.
