| Abstract: | The reaction of copper(II) cysteinate with thiosemicarbazide (TSC) in water was found to yield complex of copper(II) thiocyanate of the Cu(TSC)2(SCN)2] composition, whose crystal structure was determined by X-ray crystallography. Crystals of the complex are triclinic with a = 6.040 Å, b = 7.112 Å, c = 8.276 Å, α = 91.34°, β = 101.72°, Γ = 114.83°, Z = 2, space group \(P\bar 1\). Structural units of the complex are Cu(TSC)2]2+ centrosymmetric cations and (SCN)? anions linked by hydrogen bonds (HB), as well as by electrostatic and π-π stacking interactions. The coordination polyhedron of Cu atoms is a square completed to bipyramid; the bonds Cu(1)-N(3), Cu(1)-S(1), and Cu(1)-S(2) are 2.002 Å, 2.303 Å, and 3.015 Å, respectively. |
