Ethyl 3-(4-chlorophenyl)-2-phenyl-3-(4-phenyl-1,2,3-selenadiazol-5-yl)propanoate

Crystal structures of the heavier main group elements in low oxidation states have been evaluated for the presence of supramolecular element(lp)⋯π(arene) interactions that are structure-directing. It is revealed that when present, these interactions lead to zerodimensional, binuclear aggregates but higher-nuclearity species are sometimes observed, with one-dimensional supramolecular chains of varying topology being prominent. By contrast, two-dimensional aggregation based on element(lp)⋯π(arene) interactions are rare. In summary, interactions of main group metal lone-pairs with aromatic rings are revealed as synthons capable of assembling molecules into supramolecular aggregates. † Electronic supplementary information (ESI) available: For ESI (illustrations of supramolecular aggregation based on main group element(lone-pair)⋯π(arene) interactions for 1-157), see DOI:

Ethyl 3-(4-chlorophenyl)-2-phenyl-3-(4-phenyl-1,2,3-selenadiazol-5-yl)propanoate

Abstract: In the title compound, C25H21ClN2O2Se, the selenadiazole ring is almost planar [maximum deviation = 0.004 (2) Å], and the adjacent benzene ring is twisted by 50.6 (1)° with respect to this ring.
