ADDITION-COMPOUNDS OF DICHLORODIOXOMOLYBDENUM(VI) FROM HYDROCHLORIC-ACID SOLUTIONS OF MOLYBDENUM TRIOXIDE - CRYSTAL-STRUCTURE OF DICHLORODIOXODIAQUAMOLYBDENUM(VI) BIS(2,5,8-TRIOXANONANE)

The behaviour of hydrochloric acid solutions Of MoO3 with some common solvents has been explored. MoO2Cl2(H2O)2 separates from solution stab ilized as polyether solvates. The crystal structure of [MoO2Cl2(H2O)2( 2,5,8-trioxanonane)2] presents octahedral MoO2Cl2(H2O)2 Units linked t o the polyether chains through hydrogen bonds involving the water mole cules. The polyether molecules show a cis-cis conformation.
