Abstract
The crystal structure of Ca2Al(OH)6Cl · 2H2O was determined by single crystal structure analysis (M = 433.344, C2/c, a0 = 9.979(3) Å, b0 = 5.751(2) Å,c0 = 16.320(6) Å, β = 104.53(3)°, V = 906.64 Å3, Z = 4, Dx = 2.056 g/cm3*, MoKα = 0.70926, μ = 16.276 cm−1, F(000) = 576, room temperature, R = 0.035, Rw = 0.040 for 986 reflexions). The structure consists of alternate slices of Al(OH)6 octahedra connected by Ca atoms and planes of Cl atoms that are linked by hydrogen bonding. The water molecule completes the coordination polyhedron of Ca (O atom) and connects the Cl arrangement to a close packed net (H atoms).Keywords
