New salts of oxohalomolybdate(V) ions, 5-nitro 1,10-phenanthroline oxopentachloro- and pentabromo molybdates, (5-nitrophenH₂) [MoOX₅] (X=CI, Br), have been isolated in pure form for the first time. Reactions of these salts both in solution and in solid state lead to the synthesis of nonelectrolytic cis·[MoOX₃.5-nitropben], oxalato derivative [MoO.OX.CI.5-nitrophen] and hydrolytic products [Mo₂O₄X₂(5-nitrophen)₂]. These compounds have been characterised by analytical and other physico-chemical techniques.
