The ability of (PNNH)CoCl2(where PNNH is a phosphino and pyrazole substituted pyridine pincer) to serve as a precursor to coordinate the weak anion nitrate is investigated, giving a product with two coordinated nitrates, which demonstrate remarkable variability of nitrate binding in an overall six coordinate divalent cobalt complex. A synthetic variant with only one chloride per Co(II) is characterized, and retains coordination number 5. Comparison is made to rhodium, initially in oxidation state +1, including a carbonyl reporter ligand. The tridentate pincer displaces chloride and PPh3from Rh(PPh3)2(CO)Cl to form the salt [(PNNH)Rh(CO)]Cl. That compound reacts withN-chloro succinimide with oxidation to trivalent rhodium, loss of carbon monoxide, but also with inadvertent chlorine substitution of pyrazole ring CH bond. As a comparison standard for PNNH ligand with a redox inert metal, (PNNH)ZnCl2is characterized; bond lengths within the ligand allow the conclusion that the iron and cobalt analogs show no major back donation into the pincer ligand.
