Abstract
- Reaction of 2,4,6-tris(2-pyrimidyl)-1,3,5-triazine (TPymT) with Pb(NO<subscript>3</subscript>)<subscript>2</subscript> in aqueous medium leads to the formation of a mixture of two pseudopolymorphs, {[Pb<subscript>2</subscript>(TPymT)(H<subscript>2</subscript>O)(NO<subscript>3</subscript>)<subscript>4</subscript>]·H<subscript>2</subscript>O}<subscript>n</subscript>, 1 and [Pb<subscript>2</subscript>(TPymT)(NO<subscript>3</subscript>)<subscript>4</subscript>]<subscript>n</subscript>, 2, where TPymT molecules are coordinated with two PbII ions in a bridging bis-terpyridine fashion. We demonstrate that fast evaporation of the solvent leads exclusively to the formation of 1, while 2 was formed upon slow evaporation. The two pseudopolymorphs can be interconverted by dissolving in water upon heating and controlling the evaporation rate. [ABSTRACT FROM AUTHOR]
