Abstract

The crystal and molecular structure of FeCl(S2CN(CH2)5)2CHCl3 were solved by the X-ray structural analysis method and refined to R 0.073 for 1996 observed independent reflections. The compound crystallizes in a space group of symmetry P1 with the following unit cell dimensions: a = 0.6384 (5), b = 1.475 (1), c = 1.1966 (6) nm, α = 86.20 (5), β = 95.24 (6), γ = 97.45 (6)°. The experimentally measured density of the crystals of the substance is 1.60 Mgm-3 and the value calculated for Z = 2 is 1.59 Mgm-3. The basic skeleton structure is formed by the complex molecules forms closed cavities filled with chloroform molecules. The central Fe(III) ion is characterized by a quartet ground state (S = 3/2) and is pentacoordinated by a chlorine atom and 4 sulphur atoms in a tetragonal bipyramidal arrangement. The complex-chloroform interaction depends on formation of a double-branched hydrogen bond of the chloroform proton with two sulphur atoms in the coordination polyhedron.
