N2 - The title cation has been prepared in aqueous solution by a previously described method, isolated on a cation-exchange resin, and eluted with 0.2 M trifluoromethanesulfonic acid. In separate experiments done in different laboratories by different workers crystals with the same composition, [MO3O(CCH3)(O2CCH3)6(H2O)3](CF3SO3)(CF3SO3H)2·5H2O, were obtained, but when one crystal from each batch was examined, they had slightly different cell dimensions. Both structures, 1 and 2, were refined as fully as possible and shown to contain essentially identical trinuclear cations, with dimensions identical with those previously found in a BF4− salt. For the two crystals the dimensions of the orthorhombic unit cell (space group Pmn21 and Z = 2) were as follows (where the values of 1 and 2 are given in that order for each dimension): a = 13.699 (2), 13.510 (4) Å; b = 8.092 (3), 8.059 (4) Å; c = 20.010 (12), 19.667 (6) Å; V = 2218 (2), 2141 (2) Å3. There are different arrangements of the water molecules and trifluoromethanesulfonate ions in the two forms, which entail different hydrogen-bonding schemes.
