Crystal Structure of the Triethylammonium Salt of 3-Carboxymethyl-5-[2-(3-decyl-2-benzothiazolidene)ethylidene]-2-thioxo-4-thiazolidinone

The crystal structure of the triethylammonium salt of 3-carboxymethyl-5-[2-(3-decyl-2-benzothiazolidene)ethylidene]-2thioxo-4-thiazolidinone was determined by X-ray crystallography. The compound crystallized in a triclinic system, space groups P1 and Z = 2 with cell parameters a = 11.7107(13)A, b = 15.5659(17)A, c = 15.9742(17)A, a = 89.029(2)˚, b = 84.925(2)˚, g = 76.510(2)˚, V = 2820.4(5)A 3 . The crystal structure was refined to final values of R1 = 0.0970 and wR2 = 0.2460. A negative charge assisted hydrogen bond (–)CAHB between the carboxyl groups was found.
