In the title compound, C(4)H(10)NO(+)·Br(-), which was synthesized by dehydration of diethano-lamine with HBr, morpholinium and bromide ions are linked into chains by N-H⋯Br hydrogen bonds describing a C(2) (1)(4) graph-set motif. Weaker bifurcated N-H⋯Br inter-actions join centrosymmetrically related chains through alternating binary graph-set R(4) (2)(8) and R(2) (2)(4) motifs, to form ladders along [100]. In addition, C-H⋯O inter-actions between centrosymmetric morpholinium cations link ladders, viaFormula: see text motifs, to yield sheets parallel to (101), which in turn are crosslinked by weak C-H⋯O inter-actions, related across a glide plane, to form a three-dimensional network.
在标题化合物C₄H₁₀NO⁺·Br⁻中,它是由二乙醇胺与HBr脱水合成的,吗啉鎓离子和溴离子通过N-H⋯Br氢键连接成链,描述了一个C(2) (1)(4) 图集 motif。较弱的分叉N-H⋯Br相互作用通过交替的二元图集R(4) (2)(8) 和R(2) (2)(4) motif将中心对称相关的链连接起来,沿着[100]形成梯子。此外,中心对称的吗啉鎓阳离子之间的C-H⋯O相互作用通过公式:见正文 motif连接梯子,产生平行于(101)的片层,这些片层又通过弱的C-H⋯O相互作用在滑移面两侧相关联而交联,形成三维网络。
