Transition metal ions, reaction with silane

Both PH3 and S i 114 react similarly with bare transition metal ions except that no simple addition ions [MSiELJ have so far been observed. The Cu+ ion reacts by dehydrogenation and the most unreactive ion, Mn+, does not react in its ground state. The excited-state ion forms [MnH]+. The reactions of several first-row transition metal ions with silane (117-119) have been studied by the GIB method. The major product was [MSiH2]+ for the ground-state ions Ti+, V+, Cr+, Fe+, Co+, Ni+, Cu+, and Zn+. The group 3 (IIIB) ions Sc+, Y+, La+, and Lu+ (49) all reacted with silane in a similar manner to the first-row transition metal ions.
