Four novel clusters of Co or Ni, Se, and PPh 3 have been obtained in good yields from [MCl 2 (PPh 3 ) 2 ] and Se(SiMe 3 ) 2 in toluene. In all four clusters, whose structures have been elucidated, the actual core is surrounded by a sheath of phenyl groups. The empirical formulas are given in the title; the structure of the nickel complex is to be seen on the cover page of this issue. The four complexes are 60e, 98e, 137e, and 448e species, respectively.–The longer known analogous reaction with S(SiMe 3 ) 2 gave other types of products.
