The title compound, C12H18O7, crystallizes with the anhydride moiety non-planar and in the trans,trans conformation. The stability of this compound suggests that quaternary C atoms attached to carbonyl C atoms have a stabilizing influence on acyclic anhydride compounds.

Several multifunctional derivatives of methylthiomalonic acid (= 2-(thiocarboxy)acetic acid), i.e. 20a,b, 21, 22a,b, and 24, were prepared from thiols bearing a functionalized head group, i.e. from 9a,b, 12, and 16d,f (Schemes 4 and 5). The association constants of the two dithio podands 8b and 11 with K+ were determined.
