Morpholinium 2-chloro-4-nitrobenzoate, 2-chloro-5-nitrobenzoate and 4-chloro-3-nitrobenzoate

Abstract: Morpholinium 2-chloro-4-nitrobenzoate, C₄H₁₀NO⁺·C₇H₃ClNO₄^-, (I), crystallizes in a non-centrosymmetric space group. The cations and anions are connected by N-HO hydrogen bonds to afford a 2₁ helical chain. Morpholinium 2-chloro-5-nitrobenzoate, C₄H₁₀NO⁺·C₇H₃ClNO₄^-, (II), and morpholinium 4-chloro-3-nitrobenzoate, C₄H₁₀NO⁺·C₇H₃ClNO₄^-, (III), both crystallize in a centrosymmetric space group. In (II) and (III), two cations and two anions are held together by N-HO hydrogen bonds to form a centrosymmetric ring with graph-set descriptor R⁴₄(12).

Formula: Three forms of C₄H₁₀NO⁺·C₇H₃ClNO₄^-
