A triclinic polymorph of 3-nitroanilinium chloride
The asymmetric unit of the title compound, C(6)H(7)N(2)O(2) (+)·Cl(-), contains two independent ion pairs. A monoclinic form of the title compound with only one ion pair in the asymmetric unit has been reported previously [Ploug-Sørensen & Andersen (1986). Acta Cryst. C42, 1813-1815]. In the crystal of the title compound, the components are linked into layers parallel to (001) by inter-molecula...
متن کامل1,3-Bis(3-methylphenyl)thiourea: triclinic polymorph
The title compound, C(15)H(16)N(2)S, crystallizes with two molecules in the asymmetric unit. The crystallographic behaviour of the two isomers is different. The mol-ecules are dimerized, forming an R(2) (2)(8) ring motif due to inter-molecular N-H⋯S hydrogen bonds. C-H⋯S hydrogen bonds form R(2) (2)(12) ring motifs. In one molecule, the dihedral angle between the benzene rings is 62.54 (6)°, wh...
متن کامل4,4′-Dimethoxybenzophenone: a triclinic polymorph
The title compound, C(15)H(14)O(3), has been found to crystallize as a new triclinic polymorph. The asymmetric unit of the present structure, as in the previously reported monoclinic structure [Norment & Karle (1962 ▶). Acta Cryst. 15, 873-878], contains two independent mol-ecules, which differ slightly in the orientations of the two benzene rings. The crystal packing of the triclinic polymorph...
متن کاملCalcium acamprosate: a triclinic polymorph
The title compound, poly[bis-(μ(3)-4-acetamido-propane-sulfon-ato)-calcium], [Ca(C(5)H(10)NO(4)S)(2)](n), is a triclinic polymorph of the previously reported monoclinic structure [Toffoli et al. (1988 ▶). Acta Cryst. C44, 1493-1494]. The triclinic modification was found to have an all-trans configuration of the acetamido-propane chain, in contrast with the monoclinic polymorph which shows an an...
متن کاملCrystal structure of 3-methylpyridinium picrate: a triclinic polymorph
The title mol-ecular salt, C6H8N(+)·C6H2N3O7 (-) (systematic name: 3-methyl-pyridinium 2,4,6-tri-nitro-phenolate), crystallizes in the triclinic space group P-1. The crystal structure of the monoclinic polymorph (space group P21/n) has been reported [Stilinovic & Kaitner (2011 ▸). Cryst. Growth Des. 11, 4110-4119]. In the crystal, the anion and cation are linked via bifurcated N-H⋯(O,O) hydroge...
