Abstract

A platinum(II) terpyridine complex having an enantiopure lactate anion afforded hydrated crystals l- or d-1_hyd containing infinite chains of interacting Pt centers, while their dehydration induced crystal-to-crystal transformation into l- or d-1_dehyd, respectively, exhibiting less significant Pt-Pt and/or ligand-ligand interactions. That transformation was accompanied by changes in the color as well as the photochemical reactivity of the crystals, where l-1_dehyd showed higher reactivity than l-1_hyd in the presence of amines under visible-light irradiation.
