The salts 1-(diaminomethylene)thiouron-1-ium hydrogen difluoride, C(2)H(7)N(4)S(+).HF(2)(-), (I), and bis[1-(diaminomethylene)thiouron-1-ium] hexafluoridosilicate, 2C(2)H(7)N(4)S(+).SiF(6)(2-), (II), have both been obtained from the reaction of (1-diaminomethylene)thiourea (HATU) with hydrofluoric acid. Both compounds contain extensive networks of N-H...F hydrogen bonds. The hydrogen difluoride salt contains four independent asymmetric [HF(2)](-) anions. In the hexafluoridosilicate salt, the centrosymmetric [SiF(6)](2-) anion is distorted, although this distortion is not clearly correlated with the N-H...F hydrogen-bonding network.
