[(TMEDA)Co(NO)2][BPh4] reacts with Group 1 salts of various monoanionic ligands to yield four and five coordinate Co(NO)2}10 complexes. The synthesis of the four coordinate complex of the form [LX}Co(NO)2] via salt-metathesis reactions of [(TMEDA)Co(NO)2][BPh4] with [ArNC(Me)CHC(Me)NAr}Li(OEt2)] (Ar = 2,6-di-iso-propylphenyl) is reported. In addition [(TMEDA)Co(NO)2][BPh4] reacts with either KTp∗
