A second monoclinic polymorph of 1-benzyl-N-methyl-1H-pyrrole-2-carboxamide.

ABSTRACT: In the title compound, C(13)H(14)N(2)O, the N(pyrrole)-C(H(2))-C-C torsion angle is -7.7?(3)° and the dihedral angle between the pyrrole and benzene rings is 83.6?(2)°. In the crystal, inter-molecular N-H?O hydrogen bonds link the mol-ecules into chains extending along the c axis. We have previously reported another polymorphic form of this title compound, which has the same space group with different cell parameters: a = 9.8285?(18)?Å, b = 23.588?(4)?Å, c = 9.9230?(17)?Å, ? = 90.107?(3)°, Z = 8 and V = 2300.5?(7)?Å(3) [Zeng et al. (2010 ?). Acta Cryst. E66, o2051].

In the title compound, C(13)H(14)N(2)O, the N(pyrrole)-C(H(2))-C-C torsion angle is -7.7 (3)° and the dihedral angle between the pyrrole and benzene rings is 83.6 (2)°. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains extending along the c axis. We have previously reported another polymorphic form of this title compound, which has the same space group with different cell parameters: a = 9.8285 (18) Å, b = 23.588 (4) Å, c = 9.9230 (17) Å, β = 90.107 (3)°, Z = 8 ...[more]

1-Benzyl-N-methyl-1H-pyrrole-2-carboxamide.

Project description:The asymmetric unit of the title compound, C(13)H(14)N(2)O, contains two independent mol-ecules, which differ in the twist of the phenyl ring: the N(pyrrole)-C(H(2))-C-C torsion angles are -73.0?(3) and 17.1?(3)°. In the crystal structure, mol-ecules are linked through N-H?O hydrogen bonds into chains extending along the a axis.

A second monoclinic polymorph of 2-(diformyl-methyl-idene)-3,3-dimethyl-2,3-dihydro-1H-indole.

Project description:The crystal structure of the title compound, C(13)H(13)NO(2), is a polymorph of the structure first reported by Helliwell et al. [Acta Cryst. (2006), E62, o737-o738]. It is also monoclinic (space group P2(1)/c), but with completely different cell constants. The mol-ecular conformations of these polymorphs differ by a 180° rotation of one formyl group. The present mol-ecule is planar [maximum deviation 0.089?(2)?Å] with the exception of the two methyl groups which lie on either side of the plane. There are strong intra- and inter-molecular N-H?O hydrogen bonds. The latter link pairs of mol-ecules across crystallographic centers of symmetry. Two aldehyde O atoms are brought close together [2.896?(4)?Å in this arrangement but are not hydrogen bonded. In the earlier polymorph, one formyl group is rotated by 180° to yield inter-molecular hydrogen bonding and an infinite polymeric chain. The other formyl group is involved in the same intra-molecular hydrogen bonding as has been found here.

A second monoclinic polymorph of 6-amino-1,3-dimethyl-5-[(E)-2-(methyl-sulfan-yl)benzyl-idene-amino]-pyrimidine-2,4(1H,3H)-dione.

Project description:A new monoclinic form of the title compound, C(14)H(16)N(4)O(2)S, has been identified unexpectedly during an attempt to synthesize a coordination compound. The heterocyclic ring is essentially planar (r.m.s. deviation = 0.005?Å) and makes a dihedral angle of 8.77?(5)° with the benzene ring. This is in contrast to 12.24?(7)° reported for the first monoclinic polymorph [Booysen et al. (2011 ?). Acta Cryst. E67, o1592]. An intra-molecular N-H?S hydrogen bond is observed. In the crystal, inter-molecular N-H?O hydrogen bonds link the mol-ecules into zigzag chains along the b axis. The closest distance between the centroids of symmetry-related heterocyclic rings is 3.5161?(6)?Å.

A second monoclinic polymorph of methyl 4-hydroxy-benzoate.

Project description:A second monoclinic polymorph of methyl 4-hydroxy-benzoate, C(8)H(8)O(3), is reported. The unit-cell dimensions are different from those of the previously reported monoclinic form [Vujovic & Nassimbeni (2006 ▶). Cryst. Growth Des.6, 1595-1597]. The asymmetric unit contains three crystallographically independent mol-ecules, as observed in the previous form. The crystal structure is stabilized by inter-molecular O-H⋯O and C-H⋯O hydrogen bonds and C-H⋯π inter-actions, which link the mol-ecules into a three-dimensional network.

2-Methyl-N-p-tolyl-benzamide: a second monoclinic polymorph.

Project description:The title compound, C(15)H(15)NO, (I), is a polymorph of the structure (II) reported by Gowda et al. [Acta Cryst. (2008), E64, o1494]. Compound (II) crystalllizes in the space group C2/c (Z = 8), whereas the title compound occurs in space group P2(1)/c (Z = 4). The two mol-ecular structures differ slightly in the relative orientations of their central amide group with respect to the benzoyl ring [dihedral angles of 55.99?(7) for (I) and 59.96?(11)° for (II)] and in the inclination of the benzoyl and aniline rings [88.67?(8) for (I) and 81.44?(5)° for (II)]. In the crystal structure of (I), mol-ecules are linked by N-H?O hydrogen bonds, forming C(4) chains, which are augmented by weak C-H?O inter-actions. The structure is further stabilized by C-H?? contacts involving both of the aromatic rings.

Bis(1,3-dimethyl-1H-imidazolium) hexa-fluoro-silicate: the second monoclinic polymorph.

Project description:The title compound, 2C5H9N2 (+)·SiF6 (2-), (I), crystallized as a new polymorph, different from the previously reported one (Ia) [Light et al. (2007 ▶) private communication (refcode: NIQFAV). CCDC, Cambridge, England]. The symmetry [space groups P21/n for (I) and C2/c for(Ia)] and crystal packing patterns are markedly different for this pair of polymorphs. In (I), all imidazolium cations in the lattice are nearly parallel to each other, whereas a herringbone arrangement can be found in (Ia). In (I), each SiF6 (2-) dianion forms four short C-H⋯F contacts with adjacent C5H9N2 (+) cations, resulting in the formation of layers parallel to the ac plane. In (Ia), the C-H⋯F contacts are generally longer and result in the formation of layers along the bc plane.

Second monoclinic polymorph of 4-[(1H-benzimidazol-1-yl)meth-yl]benzoic acid.

Project description:Recently, we reported the first monoclinic [Kuai & Cheng (2011). Acta Cryst., E67, o2787] and the ortho-rhom-bic polymorph [Kuai & Cheng (2011). Acta Cryst., E67, o3014] of the title compound, C(15)H(12)N(2)O(2). Another monoclinic polymorph was obtained accidentally by the hydro-thermal reaction of the title compound with manganese chloride in the presence of potassium hydroxide at 413 K. The asymmetric unit consists of four independent mol-ecules. In the crystal, O-H⋯N hydrogen bonds link the independent mol-ecules into four separate chains parallel to the b axis.

Methyl 1-benzyl-5-methyl-2,4-diphenyl-1H-pyrrole-3-carboxyl-ate.

Project description:In the title compound, C26H23NO2, the dihedral angles between the pyrrole ring and the two phenyl rings are 58.1 (6) and 71.5 (5)°. The mean planes of the 5-methyl-benzene ring and the carboxyl group are twisted by 89.5 (3) and 22.1 (9)°, respectively, from the pyrrole ring. In the crystal, weak C-H⋯O inter-actions lead to supra-molecular layers in the ab plane.

A second monoclinic polymorph of 4,4'-[butane-1,4-diylbis(nitrilo-methyl-idyne)]dibenzonitrile.

Project description:The asymmetric unit of the title Schiff base compound, C(20)H(18)N(4), contains one half-mol-ecule, lying across a crystallographic inversion centre and adopting an E configuration with respect to the C=N bonds. The imino group is coplanar with the benzene ring with a maximun deviation of 0.096 (1) Å for the N atom. Within the molecule, the planar units are parallel but extend in opposite directions from the methylene bridge. In the crystal structure, neighbouring mol-ecules are linked together by weak inter-molecular C-H⋯N hydrogen bonds involving the cyano N atoms, forming R(2) (2)(10) ring motifs.

2-{[3-Methyl-4-(2,2,2-trifluoro-eth-oxy)pyridin-2-yl]methyl-sulfan-yl}-1H-benzimidazole propan-2-ol monosolvate: a second monoclinic polymorph.

Project description:In the crystal structure of the title compound, C??H??F?N?OS·C?H?O, the mol-ecules are linked into chains along [010] via N-H?O and O-H?N hydrogen bonds. The triclinic form was reported by Ren et al. [(2011). Acta Cryst. E67, o270] and the first monoclinic form by Chen et al. [(2012). Acta Cryst. E68, o2015-o2016]. The fused five-and six-membered rings make a dihedral angle of 1.22?(2)°, while the benzene and pyridine rings make a dihedral angle of 10.15?(2)°.
