Abstract

original image

Bridging the gap: Two metal-containing moieties, [CpRuCNRuCp]+ and [Au(CN)4], are bridged through a pta ligand in the P,N coordination mode in a water-soluble, air-stable heterobimetallic coordination polymer (see picture, Au orange, Ru turquoise, C gray, N blue, P purple). This complex exhibits gel-like behavior in water, specifically a thermally controlled volume transition. pta=1,3,5-triaza-7-phosphaadamantane, Cp=cyclopentadienyl.
