Bis(methylsulfonyl)methane

Abstract

In the title compound, C3H8O4S2, the two central S—C(H2) bond lengths are almost identical [1.781 (2) and 1.789 (2) Å]. In the crystal, each mol­ecule utilizes CH2 and CH3 bonds to form weak C—H⋯O hydrogen bonds to six other mol­ecules, thus linking mol­ecules into a three-dimensional network.

Crystal structure of 5-[bis(methylsulfonyl)methyl]-1,3-dimethyl-5-(methylsulfonyl)pyrimidine-2,4,6(1H,3H,5H)-trione

“…1. The three central sulfonyl groups utilize one methyl group which have almost identical S-C bond lengths [S1-C9 1.752 (4) Å, S2-C8 1.744 4Å, S3-C10 1.762 (4) Å] and they are slightly shorter than those reported for (PhSO 2 ) 2 CH 2 (1.786 Å; Glidewell et al 1995) and for bis(methylsulfonyl)methane (1.781 Å; Awad et al 2014). Interestingly, significant elongation of the (C4-C7) bond length [1.547 (5) Å] may be attributed to interactions between the sulfonyl groups located at position C7.…”
