摘要：

Single crystals of guanylurea (1-carbamoylguanidinium) sulphate hydrate (C 2/c, a = 30.353(6), b = 6.6162(13), c = 21.204(4) angstrom, beta = 99.37(3)degrees, V = 4201.4(14) angstrom(3), T = 200 K) were obtained from a neutral aqueous solution containing guanylurea sulphate. By analogy with previously reported simple molecular guanylurea salts, the title compound builds up an array of mutually linked chains of cations and anions, with the crystal packing being largely controlled by an extensive hydrogen bonding network.
