Reactions of the potassium and tetrabutylammonium derivatives of Cr 2H(CO) 10 −, with N-donor bidentate ligands such as 1,10-phenanthroline (phen) and 2,2′-bipyridine (bpy) have been investigated. A coordination compound of general formula K[Cr 2H(CO) 10(phen) 3] is the most stable product from the reaction of the former with phen, but under certain conditions a 1 2 adduct may also be isolated. The analogous reaction with bpy leads to a single labile adduct, K[Cr 2H(CO) 10(bpy) 2]. (C 4H 9) 4N[Cr 2H(CO) 10(phen)] is formed by interaction of the latter derivative with phen, but bpy does not give the analogous adduct.
