✦ Synopsis

In the title compound [systematic name: 2,4-diamino-5-(3,4,5trimethoxybenzyl)pyrimidinium tetrafluoroborate], C 14 H 19 -N 4 O 3 + ÁBF 4 À , the trimethoprim (TMP) molecule is protonated at one of the pyrimidine N atoms. The protonated N atom and 2-amine group of the TMP cation interact with the tetrafluoroborate anion through a pair of N-HÁ Á ÁF hydrogen bonds [graph set R 2
