On Chalcogenolates. 117. Studies on Guanidinodithioformates. 4. Crystal and Molecular Structure of Guanidinodithioformic Acid Guanidinodithioformic acid crystallizes with Z = 4 in the monoclinic space group P2₁ with cell dimensions a = 4.204(3) Å, b = 10.422(5) Å, c = 12.491(5) Å, β = 93.9(3)°. The crystal and molecular structure has been determined from single crystal X-ray data at 20°C and refined to a conventional R of 0.0242. The asymmetric part of the unit cell contains two molecules in the dipolar form with different conformation. The molecules have delocated double-bonds and are linked together by N? H···S hydrogen bridges.
