General description

Infrared spectra for gaseous and polycrystalline samples of dimethylphosphinic acid at various temperatures are reported. The molecular structure of the hydrogen bonded cyclic dimer of dimethylphosphinic acid was studied by gas-phase electron diffraction at 433K.

Application

Dimethylphosphinic acid was used in preparation of microcrystalline organometallic coordination polymer.
