A monoclinic polymorph of cysteamine hydro-chloride.

ABSTRACT: THE TITLE COMPOUND (SYSTEMATIC NAME: 2-mercaptoethan-aminium chloride), C(2)H(8)NS(+)·Cl(-), the hydro-chloride salt of cysteamine, in contrast to the previously reported triclinic polymorph [Kim et al. (2002 ?). Polyhedron, 21, 225-228], crystallized in the monoclinic crystal system. In the crystal, the cysteaminium cations are linked to the chloride anions via one S-H?Cl and three N-H?Cl hydrogen bonds. Two-dimensional slab-like networks are formed, which are stacked in [100]. This arrangement is similar to that observed in the triclinic polymorph.

Hydro-nium perchlorate-dibenzo-18-crown-6 (1/1): monoclinic polymorph.

Project description:The asymmetric unit of the title compound, H(3)O(+)·ClO(4) (-)·C(20)H(24)O(6), contains two mol-ecules/ions of each species. Both dibenzo-18-crown-6 mol-ecules have a complexed hydro-nium ion inside their cavity with O-H?O and O-H?(O,O) links between the two species. The associated perchlorate anions also accept O-H?O hydrogen bonds from the hydro-nium ion. Both crown ether mol-ecules are present in a butterfly conformation with approximate C(2v) symmetry and their cavities are closed by the benzene ring of a neighbouring mol-ecule. The packing is consolidated by C-H?O and C-H?? inter-actions.

A second monoclinic polymorph of 2,4-dimethyl-anilinium chloride.

Project description:A second monoclinic polymorph of 2,4-dimethyl-anilinium chloride, C(8)H(12)N(+)·Cl(-), (I), is reported. The unit-cell dimensions differ from those of the first reported monoclinic form, (II) [Yao (2010 ?). Acta Cryst. E66, o1563]. Nevertheless, both compounds crystallize in the monoclinic space group P2(1)/n. As in (II), the protonated amine group in (I) acts as a hydrogen-bond donor to the chloride ion, forming three N-H?Cl hydrogen bonds. The result is a two-dimensional network in the ac plane. The difference in the hydrogen-bond pattern is that in (I) only 12-membered rings are formed whereas in (II), eight-membered and 16-membered rings are formed.

2-Pyridone: monoclinic polymorph.

Project description:The asymmetric unit in the title compound, C(5)H(5)NO, comprises two independent but virtually identical mol-ecules of 2-pyridone, and represents a monoclinic polymorph of the previously reported ortho-rhom-bic (P2(1)2(1)2(1)) form [Penfold (1953 ?). Acta Cryst.6, 591-600; Ohms et al. (1984 ?). Z. Kristallogr.169, 185-200; Yang & Craven (1998 ?). Acta Cryst. B54, 912-920]. The independent mol-ecules are linked into supra-molecular dimers via eight-membered {?HNC(O)}(2) amide synthons in contrast to the helical supra-molecular chains, mediated by {?HNC(O)} links, found in the ortho-rhom-bic form.

A monoclinic polymorph of theophylline.

Project description:A monoclinic polymorph of theophylline, C(7)H(8)N(4)O(2), has been obtained from a chloro-form/methanol mixture by evaporation under ambient conditions. The new polymorph crystallizes with two mol-ecules in the asymmetric unit. The structure features inter-molecular N-H?O hydrogen bonds, resulting in the formation of dimers between two crystallographically different mol-ecules; each mol-ecule acts as both donor and acceptor.

Dicyclo-hexyl-ammonium thio-cyanate: monoclinic polymorph.

Project description:The title salt, C(12)H(24)N(+)·NCS(-), represents a monoclinic polymorph of the previously reported ortho-rhom-bic form [Khawar Rauf et al. (2008 ?). Acta Cryst. E64, o366]. Two independent formula units comprise the asymmetric unit with the major difference in their mol-ecular structures relating to the relative dispositions of the cyclo-hexyl rings [dihedral angles = 79.88?(6) and 67.72?(5)°]. Further, the independent anions form distinctive patterns of hydrogen-bonding inter-actions, i.e. 2 × N-H?N versus N-H?N and N-H?S. The resulting supra-molecular architecture is a supra-molecular chain along the c axis based on a square-wave topology.

Project description:In the molecule of the title compound, C(15)H(11)NO(2), the dihedral angle between the ring systems is 81.3?(2)°. In the crystal structure, mol-ecules are held together via C-H?O inter-actions.

A monoclinic polymorph of KY(PO(3))(4).

Project description:The title compound, potassium yttrium polyphosphate, KY(PO(3))(4), was synthesized using the flux method. The atomic arrangement consists of an infinite long-chain polyphosphate organization. Chains, with a period of four PO(4) tetra-hedra, run along the a-axis direction. Two other polymorphs of this phosphate are known, in space groups P21/n and C2/c.

Crystal structure of (E)-2-(4-chloro-benzyl-idene)-3,4-di-hydro-naphthalen-1(2H)-one: a second monoclinic polymorph.

Project description:The title compound, C17H13ClO, is the second monoclinic polymorph to crystallize in the space group P21/c. The first polymorph crystallized with two independent mol-ecules in the asymmetric unit [Bolognesi et al. (1975 ▸). Acta Cryst. A31, S119; Z' = 2; no atomic coordinates available], whereas the title compound has Z' = 1. In the title polymorph, the dihedral angle between the plane of the benzene ring of the tetra-lone moiety and that of the 4-chloro-benzyl ring is 52.21 (11)°. The cyclo-hex-2-en-1-one ring of the tetra-lone moiety has a screw-boat conformation. In the crystal, mol-ecules are liked by pairs of C-H⋯π inter-actions forming inversion dimers. There are no other significant inter-molecular inter-actions present.

Naphthalene-1,8-dicarb-oxy-lic anhydride: a monoclinic polymorph.

Project description:A new type of naphthalene-1,8-dicarb-oxy-lic anhydride, C(12)H(6)O(3), was synthesized hydro-thermally. Unlike the two previously reported polymorphs, which crystallize in the ortho-rhom-bic space groups P2(1)2(1)2(1) [Shok et al. (1971). Kristallografiya, 16, 500-502; Grigor'eva & Chetkina (1975). Kristallografiya, 20, 1289-1290] and Pbca [Shok & Gol'der (1970). Zh. Strukt. Khim.11, 939-940], this present structure crystallizes in the monoclinic space group P2(1)/c. In this structure, the planar [total puckering amplitude Q = 0.0362?(15)] mol-ecules lie parallel to each other along the a axis.

A monoclinic polymorph of 1-benzoyl-4-thio-biuret.

Project description:The title compound, C9H9N3O2S, is a monoclinic (C2/c) polymorph of the previously reported triclinic structure [Kang (2013 ?). Acta Cryst. E69, o1327]. The mol-ecule is almost planar with an r.m.s. deviation of 0.069?Å from the mean plane of all non-H atoms. The benzoyl and terminal thio-urea fragments adopt a transoid conformation with respect to the central carbonyl O atom. Two intra-molecular N-H?O hydrogen bonds are present. In the crystal, N-H?O and N-H?S inter-actions link the mol-ecules into zigzag chains extending along the c-axis direction.
