The solid state supramolecular assembly of prop-2-yn-1-ol and alkynediol transition metal complexes of Pt and Mi has been examined in light of the intermolecular interactions and hydrogen-bonding patterns established by alkyne monoalcohols and diols in the solid state. The analysis has been based on the crystal structure determination of the alcohols 1,1-dimelthyl-3-tert-butylprop-2-yn-1-ol (1), tert-butylbis(ethyl)prop-2-yn-1-ol (2), tert-butylcyclohexylprop-2-yn-1-ol (3), and tetramethylalk...The solid state supramolecular assembly of prop-2-yn-1-ol and alkynediol transition metal complexes of Pt and Mi has been examined in light of the intermolecular interactions and hydrogen-bonding patterns established by alkyne monoalcohols and diols in the solid state.

Intermolecular and intramolecular hydrogen bond distances have been shown to depend on the type of alcohols, differences having largely a steric origin. The change-in the Raman/IR stretching frequency of the C=C bond upon coordination of alkynediols to the metal centers has been examined for the nickel compounds and shown to provide a diagnostic tool for recognition of hydrogen-bond formation and typology. » weiterlesen» einklappen
