Complex [Cu(bztzt)(Hbztzt)(PPh~3)] was synthesized by electrochemical oxidation of copper in an acetonitrile solution of benzo-1,3-thiozoline-2-thione (Hbztzt) and triphenylphosphine (PPh~3), and characterized by elemental analysis and IR spectrum. The complex was dissolved in CS~2, from which yellow crystal formed. The structure of the crystal was shown to be [Cu(bztzt)(Hbztzt)(PPh~3)]· CS~2 by an X-ray structure determination. Crystal is triclinic, space group P1, with a=1.0159(2) nm, b=1.4200(2) nm, c=1.8072(3) nm, α=78. 12(1)°,β=86.56(1)°, γ=67.65(1)°, Z=2. The structure was refined to R=0.0348 and R~w=0.0316 for 4869 reflections. The copper atom is pseudotetrahedrally coordinated by two P atoms from PPh~3 and two exocyclic S atoms from bztzt^- and Hbztzt ligands respectively. The ligands of bztzt^- and Hbztzt were "averaged" by the presence of hydrogen bond (N-H…N) between them. The bond distances of two Cu- S are 0.2372nm and 0.2410nm.
