Abstract

Disclosed herein are complex transition metal hydrides of the formula EQU (PR.sub.3).sub.x (R'.sub.2 PR"PR'.sub.2).sub.y MH.sub.z Wherein: PA1 M is Nb, Ta, Ti, Zr, or Hf PA1 R is alkyl or aryl of up to 8 carbon atoms PA1 R' is alkyl or aryl of up to 8 carbon atoms PA1 R" is alkylene of up to 3 carbon atoms, or o-phenylene With the provisos that: When PA1 M is Nb or Ta, PA1 x = 0, 1,2 or 4; y = 0, 2 or 3; z = 1, 3 or 5; and 2x + 4y + z = 13 and When M is Ti, Zr or Hf, PA1 x = O, y = 1, and z = 3. Also taught is a process for making these hydrides.
