Structure of the co-crystalline solid formed between 1,4-dichloronaphthalene-2,3-diol and dioxane

摘要: The 1,4-dichloro-(1) and 1,4-dibromo-(2) derivatives of naphthalene-2,3-diol crystallise in structures containing acetic acid or dioxane solvent molecules. X-ray crystallographic examination the compound formed between1 is reported here [(C10H6Cl2O2)2·(C4H8O2),P21/c,a=12.358(3),b=4.9930(7),c=19.167(4) A,β=96.09(1)0,Z=2,R=0.035] this structure analysed crystal engineering terms. a co-crystalline material involving two types hydrogen bonding: one phenolic group participates a $$\begin{gathered} ...{\text{OH }}...{\text{OH }}...{\text{OH}} \hfill \\ {\text{ | |}} Ar Ar}} \end{gathered} $$ chain, while second bonds to dioxane. Extension bonding network through oxygen results heavily corrugated layers. Neighbouring layers interact by combination aromatic face-face edge-face interactions similar partial coronene-type γ packing complete structure.
