A second monoclinic polymorph of N-[bis-(morpholin-4-yl)phosphino-yl]-4-fluoro-benzamide with the P2(1)/n space group.

ABSTRACT: A second monoclinic polymorph of the title mol-ecule, C(15)H(21)FN(3)O(4)P, is reported in the space group P2(1)/n and compared to the previously reported C2/c space group [Gholivand et al. (2006 ?). Polyhedron, 25, 711-721]. The asymmetric unit of the title compound consists of two independent mol-ecules. The P atoms adopt a distorted tetra-hedral environment. In the C(O)NHP(O) fragment, the P=O and the N-H groups are in a syn conformation with respect to each other and in the crystal, inter-molecular N-H?O=P hydrogen bonds form dimeric aggregates.

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.

A monoclinic polymorph of N-(3-chloro-phen-yl)benzamide.

Project description:The title compound, C(13)H(10)ClNO, (I), is a polymorph of the structure, (II), first reported by Gowda et al. [Acta Cryst. (2008), E64, o462]. In the original report, the compound crystallized in the ortho-rhom-bic space group Pbca (Z = 8), whereas the structure reported here is monoclinic P21/c (Z = 4). The principal difference between the two forms lies in the relative orientations of the phenyl and benzene rings [dihedral angle = 8.90 (13)° for (I) and 61.0 (1)° for (II)]. The inclination of the amide -CONH- units to the benzoyl ring is more similar [15.8 (7)° for (I) and 18.2 (2)° for (II)]. In both forms, the N-H bonds are anti to the 3-chloro substituents of the aniline rings. In the crystal, inter-molecular N-H⋯O hydrogen bonds form C(4) chains along c. These chains are bolstered by weak C-H⋯O inter-actions that generate R(2) (1)(6) and R(2) (1)(7) ring motifs.

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.

A second monoclinic polymorph of N-(pyrazin-2-yl)aniline.

Project description:The two aromatic rings in the title compound, C(10)H(9)N(3), are aligned at 23.4 (1)° and the bridging C-N-C angle is 128.9 (1)°. In the crystal structure, intermolecular N-H⋯N hydrogen bonds result in a chain motif, the repeat distance of which is half the b axial length of 8.8851 (3) Å.

A second monoclinic polymorph of (E)-phen-yl(pyridin-2-yl)methanone oxime.

Project description:The title compound, C(12)H(10)N(2)O, a second monoclinic poly-morph of (E)-phen-yl(pyridin-2-yl)methanone oxime crystallizes in the space group P2(1)/n (Z = 4). The previously reported polymorph [Taga et al. (1990 ▶). Acta Cryst. C46, 2241-2243] occurs in the space group C2/c (Z = 8). In the crystal, pairs of bifurcated O-H⋯(N,O) hydrogen bonds link the mol-ecules into inversion dimers. The dimers are linked by C-H⋯π inter-actions, forming a linear arrangement. The dihedral angle between the pyridine and phenyl rings is 67.70 (8)°.

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.

2,2'-(1,3-Diazinane-1,3-di-yl)diaceto-nitrile: a second monoclinic polymorph.

Project description:A new monoclinic polymorph of the title compound, C(8)H(12)N(4), in the space group P2(1)/n (Z = 4) is reported. The previously known form was also monoclinic, P2(1)/c (Z = 4), but the unit-cell parameters and crystal packing were different [Shoja & Saba (1993 ?). Acta Cryst. C49, 354-355]. The hexa-hydro-pyrimidine ring of the title compound adopts a chair conformation with a diequatorial substitution and with the CH(2)-C N groups oriented nearly parallel and in the same direction [NC-CH(2)?CH(2)-CN pseudo torsion angle = -6.27?(18)°]. In the crystal, inter-molecular C-H? N hydrogen bonds connects the mol-ecules into a chain along the b axis.

N-(2-Formyl-phen-yl)-4-toluene-sulfonamide: a second monoclinic polymorph.

Project description:The title compound, C(14)H(13)NO(3)S, (I), is a second monoclinic polymorph. The original polymorph, (II), was reported by Mahía et al. [Acta Cryst. (1999), C55, 2158-2160]. Polymorph (II) crystalllized in the space group P2(1)/c (Z = 4), whereas the title polymorph (I) occurs in the space group P2(1)/n (Z = 4). The dihedral angle between the two aromatic rings is 75.9 (1)° in (I) compared to 81.9 (1)° for (II). In both polymorphs, two S(6) rings are generated by intra-molecular N-H⋯O and C-H⋯O hydrogen bonds, resulting in similar mol-ecular geometries. However, the two polymorphs differ concerning their crystal packing. In (I), mol-ecules are linked into C(8) zigzag chains along the b axis by C-H⋯O hydrogen bonds, whereas in (II) mol-ecules are linked by C-H⋯O hydrogen bonds, forming C(7) chains along the b axis. The title polymorph is further stabilized by inter-molecular C-H⋯π and π-π inter-actions [centroid-centroid distance = 3.814 (1) Å]. These inter-actions are not evident in polymorph (II).

A second monoclinic polymorph of N-(2,4-dinitro-phen-yl)-2,4-dinitro-aniline.

Project description:The title compound, C(12)H(7)N(5)O(8), was previously described in space group P2(1)/n with Z = 4 [Wu et al. (2007 ?). Acta Cryst. E63, o4194]. The current monoclinic P2(1)/c polymorph was obtained from a mixed solution of dichloro-methane and hexane. The dihedral angle between the benzene rings is 44.16?(5)°, smaller than in the previously reported polymorph [56.3?(2)°]. As a result of the steric hinderance of the nitro groups, hydrogen bonding is limited intramolecularly. The dihedral angles between the phenyl rings and their attached nitro groups are 18.97?(6) and 17.71?(5)° at the 2-position, and 18.52?(6) and 32.41?(6)° at the 4-position.

Diosgenone: a second P2(1) polymorph.

Project description:Diosgenone [(20S,22R,25R)-spirost-4-en-3-one, C(27)H(40)O(3)] has been proposed as a new therapeutic alternative for the treatment of malaria. The first X-ray structure report for diosgenone was by Piro et al. [(2002). Z. Naturforsch. Teil C, 57, 947-950] in the space group P2(1) (Z' = 2). We now report a new polymorph in the same space group, with two mol-ecules in the asymmetric unit. Both mol-ecules have similar conformations, characterized by a skewed envelope A ring, which contains the C=C bond conjugated with the ketone functionality at C3. The dimorphism results from a modification of the relative orientation of the mol-ecules in the asymmetric unit: two independent mol-ecules were arranged anti-parallel in the Piro report, while they are parallel in the present determination.
