The synthesis, structural features and thermal behaviour of thiophene-containing dithiocarboxylate complexes of zinc(II)
摘要:
The complexes [Zn-2(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. (c) 2006 Elsevier Ltd. All rights reserved.
