N1 - Funding Information: The only two infrared peaks observed by us between 1700 and 2200 cm.-l are those a t 2085 and 2105cm.-l noted above. It may be that these correspond to the Co-H and N-N stretching frequencies, and that previous workers failed to resolve these two peaks. Although several metal- hydrogen stretching frequencies have been observed in the 2100cm.-l region, this is about 100-200 cm.-l higher than Co-H stretching fre- quencies in various carbonyl and phosphine complexes. Yet it seems possible that the Co-H stretching frequency could be higher when H is tvans to N,, rather than to CO. \Ye are continuing our attempts t o prepare another crystal suitable for diffraction study. IT'ith counter data from a suitable crystal it should be possible to furnish unambiguous evidence concerning the presence of a Co-H bond. It'e thank Professor J. Chatt for his interest and assistance and the U.S. National Science Founda- tion for their financial support. (Received, December 6th, 1967 ; Cow. 1304.) 1 A. Yamamoto, S. Kitazume, L. S. Pu, and S.
