Abstract
Folded and unfolded solid-state structures of a bimetallic alkynylplatinum terpyridine complex with a flexible terthiophene linker have been obtained. Weak intermolecular interactions including π-π stacking and C-H···O and C-H···Cl interactions as well as Cl-π interactions stabilize the folded structure. In solution, folding is studied by electronic absorption spectroscopy and (1)H and NOESY NMR experiments.
