“…Metal methanesulfonates initially attracted attention for their catalytic properties in various organic synthesis reactions. , A number of the compounds have been reported, encompassing diverse metals (M), including alkali metals (M = Li, Na, K, Rb, Cs), , alkaline-earth metals (M = Mg, Ca, Sr, Ba), , transition metals (M = Mn, Cu, Zn, Ag, Cd etc. ), , and post-transition metals (M = Ge, Sn, Pb, Hg). − There are only three reported bimetallic methanesulfonates, MAu(CH 3 SO 3 ) 4 (M = Li, Na, Rb) . To the best of our knowledge, metal methanesulfonates with mixed anions or anionic groups have not been reported.…”
