| Abstract: | The complexes Zn2(S2CTR)4] (T = 2,5-disubstituted thiophene, R = C4H9 (1), C6H13 (2), C8H17 (3), C12H25 (4) and C16H33 (5)) have been synthesized and their structural features investigated. Compared to the analogous dithiobenzoate complexes, the crystal structure determination of 2 revealed that the thiophene induces a “step-rod” chain pattern instead of the linear, rodlike structure found for the corresponding dithiobenzoates. Complexes 1–5 did not display mesophases under thermal conditions, but an irregular melting pattern was observed for 3 and 4. |
