Crystal Structure of Metformin·ethyl N-(3-tossulfonyl)carbamate

Abstract

The title compound, C14H24N6O4S, was prepared by the reaction of ethyl N-(3-tossulfonyl)carbamate with metformin. It was crystallized in the triclinic system, space group P1 with a = 6.894(3)A, b = 8.323(4)A, c = 17.184(8)A, α = 84.119(7)°, β = 84.028(6)°, γ = 75.479(6)°, V = 946.4(7)A3, Z = 2, R = 0.0426. The molecules are linked by two kinds of hydrogen-bonds, N-H…N and N-H…O, generating an extended two-dimensional supramolecular network structure in the ab plane.
