Abstract
The crystal structure of the title compound contains a very long C-H . .. O contact from the ethynyl group to a carbonyl ligand with a H ... O separation of 2.92 Angstrom; weakly hydrogen bonding character of th is contact is inferred from the Raman and the IR absorption spectra, s howing the long range nature of the C-H ... O hydrogen bond.
