Structural and spectroscopic characterization of 1-(diaminomethylene) thiouron-1-ium benzoate and bis(1-(diaminomethylene)thiouron-1-ium) phthalate trihydrate

The solid-state organisation of 1-(diaminomethylene) thiouron-1-ium benzoate (1) and phthalate trihydrate (2) has been analysed with respect to cation-anion and hydrogen bonding interactions. The oppositely charged units interact via hydrogen bonds with the graphs of R22(8) and R21(6).
