Crystals of guanidinium oxalate monohydrate (GUOM), a salt of a functional guanidine derivative, crystallising with the space group of P21/c, is synthesised and characterised by single-crystal XRD, NMR, UV-Vis and vibrational spectroscopy. The assignment of spectral bands is carried out in terms of the fundamental modes of vibration of the guanidinium cation and oxalate anion. Thermal analysis (TG/DTA) indicates that the compound is thermally robust. GUOM also exhibits antimicrobial activity against a few microorganisms.
