The crystal structure of diguanidinium hexafuorosilicate, [C(NH2)3]2SiF6, consists of regular octahedral SiF62− anions linked through a system of hydrogen bonds to the guanidinium cations which have a planar conformation. The striking feature of the structure is the high degree of hydrogen bonding. All hydrogen atoms of the guanidinium units are involved in hydrogen bonds of the type N-H
F of length 2.901 (2), 2.908 (2) and 2.891 (1) Å. Unlike other materials belonging to the family of compounds of general formula Rx(NH4 − x)2MX3, the crystals of the present compound do not display ferroelectric/ferroelastic properties.
