英文摘要	Formation of potassium cyanide clusters in the direct laser vaporization of K-3[Fe(CN)(6)] was studied by use of a TOF mass spectrometer. It was found that the positive cluster ions are due to [K(KCN)(n)](+), n = 0-37, in which magic numbers are n = 3, 13, 22, 37, whereas the negative cluster ions were assigned to [(KCN)(n)CN](-), n = 0-13, where magic numbers are n = 4, 13. These magic numbers are identical with those of alkali-halide clusters. This indicates that they have the structures 1 x 3 x 3 (n = 4), 3 x 3 x 3 (n = 13), 3 x 3 x 5 (n = 22), 3 x 5 x 5 (n = 37) as those of alkali-halide clusters. Thus the formation process of potassium cyanide clusters should go along the growth course of the rock salt structure. (C) 1997 Elsevier Science B.V.
