Self-assembly of a columnar polymeric calcium phosphinate derived from camphene
Abstract
(2,2-Dimethylbicyclo[2.2.1] hept-3-ylmethyl)phosphinic acid (RPO2H2), readily prepared from camphene and hypophosphorous acid, formed a polymeric calcium salt [{Ca(RPO2H)2(RPO2H2)(H2O)}n], with both terminal and triply bridging phosphinate groups, and an overall columnar structure with an inorganic core and a pseudo-close-packed sheath of terpene moieties.
