Expanding the 2,2′-bipyrimidine bridged 1D homonuclear coordination polymers family: [MII(bpym)Cl<inf>2</inf>] (M = Fe, Co) magnetic and structural characterization

One pot reaction of hydrated chloride salts of Fe(ii) and Co(ii) with stoichiometric amounts of 2,2′-bipyrimidine (bpym) in a methanol-acetonitrile mixture afforded the corresponding 1D homonuclear coordination polymers, [μ-(bpym)MCl<inf>2</inf>]<inf>n</inf>. Crystal structur...
