The hexa - mercaptobenzoxazole - 2 - thiophene carboxylic acid ester (1) and hexamethylbenzodiazepine 2 - diazole are synthesized by the reaction of tribenzyl tin oxide with 2 - thiophenecarboxylic acid and 2 - The ester (2) clusters were characterized by elemental analysis, IR and single crystal X-ray diffraction.The results show that compound 1 belongs to triclinic system with space group P1, a = 1. 2 76 0 (3) nm, b = 1.30 5 6 (3) nm, c = 1.334 3 (3) nm, α = 1 05.65 (3) °, β = 96.27 (3) °, γ = 97.2 0 (3) °, Z = 1, V = 2.0997 nm, Dc = 1.80 9 g / cm 3, μ = 2.097 mm -1, F 0 0) = 1 1 1 6, R = 0 .0 6 5 1, w R = 0 .1 2 92. Compound 2 belongs to triclinic system with space group P1, a = 1 .2 2 4 0 (4) nm, b = 1.36 73 (4) nm, c = 1.374 4 (4) nm, α = 10.76 0 (4) °, β = 98.0 6 9 (5) °, γ = 91.4 (0 0 0) = 2 1 36, R = 80 (5) °, Z = 2, V = 2 .1 6 31 (1 2) nm3, Dc = 3.373 g / cm3, μ = 0 .0 382 and w R = 0 .0 79. Both of them are in the form of a drum-shaped cluster and the tin atoms are distorted octahedron. Compound 1 acts as a close-chain intermolecular S ... S to form a one-dimensional chain structure .
