Abstract
The X-ray diffraction study of a single crystal with the composition NiTiF6(Ur)2·7H2O is performed, where Ur = C6H12N4 is an urotropine (hexamethylenetetramine) molecule. The compound crystallizes in the triclinic P-1 space group: a = 8.7220(5) Å, b = 9.1004(5) Å, c = 17.533(1) Å, α = 75.074(1)°, β = 88.530(1)°, γ = 62.558(1)°, Z = 2, dx = 1.756 g/cm3, μ = 1.228 mm-1, R = 0.0351. The crystalline compound is ionic. The structural unit consists of [Ni(OH2)6]2+ and [TiF6]2- ions and Ur and H2O molecules. The structural formula of the compound is [Ni(OH2)6][TiF6](Ur)2·H2O. Hydrogen bonds in the compound are studied and analyzed.
