“…Although the unit-cell parameters of DMABA have been reported (Reffner & McCrone, 1959), to our knowledge there is no report on the crystal structure of DMABA. The crystal structures of DMABA hydrobromide (Dattagupta & Saha, 1973), a 1:1 complex in which DMABA acts as a guest molecule in channels (Herbstein et al, 1984), a tin complex in which DMABA serves as a ligand coordinating through its O atom (Mahadevan et al, 1982), and of a 1:1 cocrystal of DMABA and 6-phenyl-1,3,5-triazine-2,4-diamine (Habibi et al, 2007) have been reported. We report here the crystal structure of the title compound.…”
