英文摘要: Abstract(#br)Thiourea is known to act as a template to preorganise a series of trans -1,2-bispyridyl ethylenes (bpe), where the thiourea molecules present in an infinite zigzag chain with R 2 2 (8) graph set (the β-tape) which offers three different types of hydrogen bonding [J. Am. Chem. Soc. 132 (2010) 13434]. This article reports a new cocrystal of thiourea with 3,4′-bpe and acts as a ‘ missing link ’ in the series. In this cocrystal, thiourea present in an infinite corrugated chain with R 2 1 (6) graph set, a rarely observed thiourea synthon i.e . α-tape. A comparative study has been discussed which demonstrates various types of hydrogen bonding that exist in the series and their impact on the parallel stacking of the pyridyl based olefins.
