Synthesis of [Cu2Cl2(BMTTE)]2 (2)

A mixture of CuCl2·2H2O (2.7 mmol) and BMTTE (0.9 mmol) in H2O (5–15 mL) was sealed in a 20-mL Teflon-lined autoclave and heated to 160 ◦C over 100 min. The autoclave was kept at 160 ◦C for 3 days and then slowly cooled to room temperature at a rate of 10 ◦C/h. Yellow single crystals of **2** were obtained.

Data for **2**: Yield: 32%. MP: 200–202 ◦C. Anal. calc. for C12H20Cl4N16S4Cu4 N 24.7%, C 15.9%, H 2.2%; Found: N 24.3%, C 15.7%, H 2.1%. IR (cm−1): 1467m, 1406m, 1382m, ν(ring); 1296m ω(CH,CH2); 1173m δ(CH); 1147w, 1097w, 1078w, δ(ring); 728m, γ(CH); 704vs ν(C–S).
