M/sub 2/NpCl/sub 5/, MNp/sub 2/Cl/sub 7/ (M = K, NH/sub 4/, Rb) and NpCl/sub 3/ 4CH/sub 3/CN were prepared by zinc amalgam reduction of NpCl/sub 4/-MCl in 50:1 acetonitrile-propionic acid solutions. The /sup 237/Np Moessbauer spectra of these compounds showed quadrupole interactions, with Moessbauer parameters delta = 3.4 to 3.5 cm/sec and 1/4eqQ = 0.5 to 0.7 cm/sec. Moessbauer spectra established that preparations analyzing as MNpCl/sub 4/ CH/sub 3/CN were mixtures of M/sub 2/NpCl/sub 5/ and NpCl/sub 3/ 4CH/sub 3/CN.
