Trithiacyanuric acid: a second triclinic polymorph
The title compound, C(3)H(3)N(3)S(3), is a triclinic modification. The other reported modification crystallizes with just one mol-ecule in the asymmetric unit, [Guo et al. (2006 ▶). Cryst. Growth Des.6, 846-848] and was solved by power X-ray diffraction data. The present modification has Z' = 2. In the crystal, mol-ecules are linked by strong intra-molecular N-H⋯S hydrogen bonds with set graph-...
متن کاملA second triclinic polymorph of azimsulfuron
The title compound, C13H16N10O5S (systematic name: 1-(4,6-di-meth-oxypyrimidin-2-yl)-3-{[1-methyl-4-(2-methyl-2H-tetra-zol-5-yl)pyrazol-5-yl]sulfonyl}urea), is a second triclinic polymorph of this crystal [for the other, see: Jeon et al., (2015 ▸). Acta Cryst. E71, o470-o471]. There are two mol-ecules, A and B, in the asymmetric unit; the dihedral angles between the pyrazole ring and the tetra-...
متن کاملA triclinic polymorph of hexanedioic acid
Hexane-dioic acid (or adipic acid), C(6)H(10)O(4), crystallizes with two crystallographically independent half-mol-ecules in the asymmetric unit of the triclinic unit cell, space group P, as each mol-ecule lies across a crystallographic inversion centre. A monoclinic polymorph has been reported previously, most recently by Ranganathan, Kulkarni & Rao [J. Phys. Chem. A, (2003), 107, 6073-6081]. ...
متن کاملA second triclinic polymorph of (1-ammonio-1-phosphonoethyl)phosphonate
The asymmetric unit of the second polymorph of the title compound, C(2)H(9)NO(6)P(2), contains one mol-ecule existing as a zwitterion. The N atom of the ammonio group is protonated and one of the phospho-nic acid groups is deprotonated. Bond lengths and angles are similar in both polymorphs. Besides the differences in cell parameters, the most significant structural difference between this stru...
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...
