Diethyl [(4-bromophenyl)(5-chloro-2-hydroxyanilino)methyl]phosphonate
In the title compound, C(17)H(20)BrClNO(4)P, inter-molecular C-H⋯O and N-H⋯O hydrogen bonds form centrosymmetric R(2) (2)(10) dimers linked through O-H⋯O inter-molecular hydrogen bonds, which form centrosymmetric R(2) (2)(16) dimers. All these hydrogen bonds form chains along [010]. In addition, the crystal structure is stabilized by weak C-H⋯Br hydrogen bonds. The very weak intramolecular N-H⋯...
متن کاملDiethyl [(5-chloro-2-hydroxyanilino)(4-chlorophenyl)methyl]phosphonate
In the title compound, C(17)H(20)Cl(2)NO(4)P, the P atom is bonded in a distorted tetra-hedral environment. The dihedral angle between the two benzene rings is 80.5 (1)°. In the crystal structure, inter-molecular O-H⋯O and N-H⋯O hydrogen bonds link pairs of mol-ecules into centrosymmetric dimers. These dimers, are in turn, linked by weak inter-molecular C-H⋯O hydrogen bonds into one-dimensional...
متن کامل1,10-Phenanthrolinium 4-chloro-2-hydroxybenzoate–1,10-phenanthroline–4-chloro-2-hydroxybenzoic acid (1/1/1)
The title compound, C(12)H(9)N(2) (+)·C(7)H(4)ClO(3) (-)·C(12)H(8)N(2)·C(7)H(5)ClO(3), contains one phenanthrolinium (Hphen) cation, one phenanthroline (phen) mol-ecule, one 4-chloro-2-hydroxy-benzoate anion (hcba) and one 4-chloro-2-hydroxy-benzoic acid (Hhcba) mol-ecule in the asymmetric unit. The phen mol-ecule is approximately parallel to Hphen, making a dihedral angle of 1.98 (6)°. The cen...
