Bruce, R. St. L. published the artcileLinkage isomers of molybdenum and the chelate ligand pyridine-2-carboxaldehyde-2′-pyridylhydrazone (paphy), Application In Synthesis of 2215-33-0, the publication is Journal of the Chemical Society [Section] D: Chemical Communications (1970), 69-70, database is CAplus.
Direct reaction of paphy with Mo(CO)6 in diglyme at 128° gave orange-red air-stable I, while reaction of tetraethylammonium chloropentacarbonylmolybdenum(0) with paphy in diglyme at room temperature gave II.
