TY - JOUR A1 - Tutughamiarso, Maya Oktavia A1 - Bolte, Michael T1 - 2-Amino-1-methyl-1H-imidazol-4(5H)-one dimethyl sulfoxide monosolvate T2 - Acta crystallographica / Section E, Structure reports online N2 - In the title compound, C4H7N3O·C2H6OS, creatinine [2-amino-1-methyl-1H-imidazol-4(5H)one] exists in the amine form. The ring is planar (r.m.s. deviation for all non-H atoms = 0.017 Å). In the crystal, two creatinine mol­ecules form centrosymmetric hydrogen-bonded dimers linked by pairs of N—H[cdots, three dots, centered]N hydrogen bonds. In addition, creatinine is linked to a dimethyl sulfoxide mol­ecule by an N—H[cdots, three dots, centered]O inter­action. The packing shows layers parallel to (120).
