Abstract
Graphic
Co-crystallization of 1,2-dihydroxybenzene (cat) with
trans-1-(2-pyridyl)-2-(4-pyridyl)ethylene (2,4-bpe) gives a layered ternary solid, (cat)·(2,4-bpe)·(H
2O)
1, with molecular components held together by a combination of O–H⋯N and O–H⋯O forces wherein 2,4-bpe is organized for a ‘head-to-tail’ (ht) [2+2] photocyclodimerization. UV-irradiation of the solid produces
rctt-1,3-bis(2-pyridyl)-2,4-bis(4-pyridyl)cyclobutane [
rctt-(2,4-tpcb-ht)] in quantitative yield. The structure of
rctt-(2,4-tpcb-ht), in the form of crystalline
rctt-(2,4-tpcb-ht)·1.5(H
2O), has been confirmed by way of single-crystal X-ray diffraction.
