Ortho-rhom-bic polymorph of (6,7-dimeth-oxy-1,2,3,4-tetra-hydro-isoquinolin-1-yl)methanol.

ABSTRACT: The asymmetric unit of the title compound, C(12)H(17)NO(3), contains two mol-ecules with different conformations. It is a polymorph of the monoclinic form [El Antri et al. (2004 ?). Mol-ecules, 9, 650-657]; the samples were crystallized at different temperatures from the same solvent. In both structures, mol-ecules are linked by O-H?N hydrogen bonds, forming chains. The conformations of the chains and their packing differ markedly in the two polymorphs.

The asymmetric unit of the title compound, C(12)H(17)NO(3), contains two mol-ecules with different conformations. It is a polymorph of the monoclinic form [El Antri et al. (2004 ▶). Mol-ecules, 9, 650-657]; the samples were crystallized at different temperatures from the same solvent. In both structures, mol-ecules are linked by O-H⋯N hydrogen bonds, forming chains. The conformations of the chains and their packing differ markedly in the two polymorphs. ...[more]

[(1R,3S)-6,7-Dimeth-oxy-1-phenyl-1,2,3,4-tetra-hydro-isoquinolin-3-yl]methanol 2.33-hydrate.

Project description:The title compound, C(18)H(21)NO(3)·2.33H(2)O, is the fourth reported member in a series of (1R,3S)-6,7-dimeth-oxy-1-phenyl-1,2,3,4-tetra-hydro-isoquinoline derivatives used in catalysis as ligands (or their precursors). The N-heterocycle in the structure adopts a half-chair conformation. The dihedral angle between the benzene rings is 77.29 (13)°. There are three ill-resolved water molecules of crystallization in the structure (one of them rotationally disordered about a threefold axis) involved in short contacts probably due to hydrogen bonding.

Project description:In the title compound, C(37)H(35)NO(3), a precursor to novel chiral catalysts, the N-containing six-membered ring assumes a half-chair conformation. Inter-molecular C-H?O hydrogen bonds link the mol-ecules in the crystal structure.

Two ortho-rhom-bic polymorphs of hydro-morphone.

Project description:Conditions to obtain two polymorphic forms by crystallization from solution were determined for the analgesic drug hydro-morphone [C17H19NO3; systematic name: (4R,4aR,7aR,12bS)-9-hy-droxy-3-methyl-1,2,4,4a,5,6,7a,13-octa-hydro-4,12-methano-benzofuro[3,2-e]iso-quinolin-7-one]. These two crystalline forms, designated as I and II, belong to the P212121 ortho-rhom-bic space group. In both polymorphs, the hydro-morphone mol-ecules adopt very similar conformations with some small differences observed only in the N-methyl amine part of the mol-ecule. The crystal structures of both polymorphs feature chains of mol-ecules connected by hydrogen bonds; however, in form I this inter-action occurs between the hydroxyl group and the tertiary amine N atom whereas in form II the hydroxyl group acts as a donor of a hydrogen bond to the O atom from the cyclic ether part.

An ortho-rhom-bic polymorph of 1-benzyl-1H-benzimidazole.

Project description:The title compound, C(14)H(12)N(2), in contrast to the previously reported monoclinic polymorph [Lei et al. (2009 ?). Acta Cryst. E65, o2613], crystallizes in the ortho-rhom-bic crystal system. The dihedral angle between the imidazole ring system and the phenyl ring is 76.78?(16)°. Weak C-H?N and C-H?? inter-actions are observed in the crystal structure.

An ortho-rhom-bic polymorph of the ultraphosphate YP(5)O(14).

Project description:Single crystals of yttrium penta-phosphate(V), YP(5)O(14), were obtained by solid-state reaction. The ortho-rhom-bic title compound belongs to the family of ultraphosphates and is the second polymorph of this composition. It is isotypic with its Ho and Er analogues. The structure contains two bridging Q(2)-type PO(4) tetra-hedra and one branching Q(3)-type PO(4) tetra-hedron, leading to infinite ultraphosphate ribbons running along the a axis. The coordination polyhedron around the Y(3+) cation may be described as distorted bicapped trigonal-prismatic. The YO(8) polyhedra are isolated from each other. They are linked by corner-sharing to the O atoms of six Q(2)-type and of two Q(3)-type PO(4) tetra-hedra into a three-dimensional framework.

An ortho-rhom-bic polymorph of 3,4-di-amino-benzo-nitrile.

Project description:The title compound, C7H7N3, is an ortho-rhom-bic polymorph that crystallizes in the space group Pca21. The previously reported monoclinic form [Geiger & Parsons (2013 ?) Acta Cryst. E69, o452] crystallizes in the space group P21/c (Z = 4). In the crystal, two independent HN-H?N C hydrogen bonds link the mol-ecules into chains along the a-glide plane. Two further independent HN-H?NH2 hydrogen bonds join the chains, forming a three-dimensional network.

An ortho-rhom-bic polymorph of cerium(III) ultraphosphate, CeP(5)O(14).

Project description:Cerium(III) ultraphosphate, CeP(5)O(14), was synthesized by a high-temperature solution reaction between CeO(2) and NH(4)H(2)PO(4) in a Ce-P molar ratio of 1:12. Colourless crystals of the ortho-rhom-bic polymorph were obtained by cooling the melt of the mixture. The structure contains (P(5)O(14))(3-) anionic ribbons linked by distorted CeO(8) polyhedra.

A second ortho-rhom-bic polymorph of 4-(Pyridin-4-ylmethoxy)phenol [corrected].

Project description:The crystal structure of the title compound, C(12)H(11)NO(2), represents a new ortho-rhom-bic polymorph II of the previously reported ortho-rhom-bic form I [Zhang et al. (2009 ▶) Acta Cryst. E65, o3160]. In polymorph II, the six-membered rings form a dihedral angle of 13.8 (1)° [71.6 (1)° in I], and O-H⋯N hydrogen bonds link mol-ecules into chains along [100], whereas the crystal structure of I features hydrogen-bonded centrosymmetric dimers.

An ortho-rhom-bic polymorph of pyrazino-[2,3-f][1,10]phenanthroline-2,3-dicarbonitrile.

Project description:The title compound, C(16)H(6)N(6), is a polymorph of the previously reported structure [Kozlov & Goldberg (2008 ▶). Acta Cryst. C64, o498-o501]. Unlike the previously reported monoclinic polymorph (space group P2(1)/c, Z = 8), the title compound reveals ortho-rhom-bic symmetry (space group Pnma, Z = 4). The mol-ecule shows crystallographic mirror symmetry, while the previously reported structure exhibits two independent mol-ecules per asymmetric unit. In the title compound, adjacent mol-ecules are essentially parallel along the c axis and tend to be vertical along the b axis with dihedral angles of 72.02 (6)°. However, in the reported polymorph, the entire crystal structure shows an anti-parallel arrangement of adjacent columns related by inversion centers and the two independent mol-ecules are nearly parallel with a dihedral angle of 2.48 (6)°.

2-[(1R,3S)-6,7-Dimeth-oxy-1-phenyl-1,2,3,4-tetra-hydro-isoquinolin-3-yl]-4-phenyl-1,3-thia-zole.

Project description:In the title compound, C(26)H(24)N(2)O(2)S, the dihedral angle between the thia-zole ring and the adjacent phenyl ring is 3.02?(15)°. The N-containing six-membered ring of the tetra-hydro-isoquinoline unit adopts a half-chair conformation. The dihedral angle between the least-squares plane of the tetra-hydro-isoquinoline ring system and its nearest phenyl ring is 76.90?(13)°. No classical hydrogen bonds nor ?-? inter-actions were found in the crystal structure.
