Abstract
In the title compound, C4H10NO+·Br−, which was synthesized by dehydration of diethanolamine with HBr, morpholinium and bromide ions are linked into chains by N—H⋯Br hydrogen bonds describing a C21(4) graph-set motif. Weaker bifurcated N—H⋯Br interactions join centrosymmetrically related chains through alternating binary graph-set R42(8) and R22(4) motifs, to form ladders along [100]. In addition, C—H⋯O interactions between centrosymmetric morpholinium cations link ladders, via(8) motifs, to yield sheets parallel to (101), which in turn are crosslinked by weak C—H⋯O interactions, related across a glide plane, to form a three-dimensional network.
