Hydrogen-bonded sheets in benzylmethylammonium hydrogen maleate

In the title compound, C8H12N+ center dot C4H3O4-, there is a short and almost linear but asymmetric O - H center dot center dot center dot O hydrogen bond in the anion. The ions are linked into C-2(2)( 6) chains by two short and nearly linear N - H center dot center dot center dot O hydrogen bonds and the chains are further weakly linked into sheets by a single C - H center dot center dot center dot O hydrogen bond.
