The structure of β(Nprim)-[Co(aet)(trien)]Cl2 [aet: 2-aminoethanethiolate, trien: triethylenetetramine] was synthesized and characterized by single-crystal X-ray analysis. The compound crystallizes in a triclinic space group P1 with a = 8.279(3), b = 10.673(5), c = 10.696(4)Å, α = 64.70(3), β = 95.76(3), γ = 91.17(4)°, V = 849.9(6)Å3, Dcalcd = 1.552 g/cm3, Z = 2. The R1 [I > 2σ(I)] and wR2 (all data) values are 0.0385 and 0.1145, respectively, for all 3913 independent reflections. Central cobalt(III) atoms have an approximate octahedral geometry and are coordinated by five nitrogen atoms and one sulfur atom. The obtained compound from the major eluate is in the β(Nprim) form in which the sulfur atom is present in the trans position to a primary nitrogen atom of the triethylenetetramine (trien).
