2,2'-[(E)-3-(4-Nitrophenyl)prop-2-ene-1,1-diyl]bis(3-hydroxy-5,5-dimethylcyclohex-2-en-1-one)

Abstract

As part of our ongoing study of the substituent effect on the solid state structures of two cyclohexenone ring derivatives (Cha et al., 2011, 2012), we present here the crystal structure of the title compound (Fig. 1). The bond lengths and angles are normal and correspond to those observed in related structures (Cha et al., 2011, 2012; Zhu et al., 2011). Both cyclohexenone rings display half-chair conformations. The hydroxy and carbonyl O atoms face each other and are oriented to allow for the formation of two intramolecular O—H···O hydrogen bonds (Table 1). In the crystal, weak intermolecular C —H···O hydrogen bonds (Table 1) are formed between molecules, generating a 2D supramolecular structure.
