A second monoclinic polymorph of N-(diethylaminothiocarbonyl)-N′-phenylbenzamidine
The asymmetric unit of the title compound, C(18)H(21)N(3)S, contains five mol-ecules. The equivalent bond distances in the five mol-ecules are in excellent agreement, the r.m.s. fit being within 0.007 Å. The five mol-ecules are linked into a chain consisting of alternating pseudo-enanti-omers by N-H⋯S hydrogen bonds supplemented by weak C-H⋯π inter-actions. The action of a glide plane links the...
متن کاملA second monoclinic polymorph of N-cyclohexyl-N-ethylbenzenesulfonamide
The crystal structure of the title compound, C(14)H(21)NO(2)S, is a polymorph of the structure reported by Khan et al. [Acta Cryst. (2009), E65, o2867] which is also monoclinic (space group P2(1)/c). The unit cell in the title structure is approximately half the volume of the previously reported polymorph and the asymmetric unit of the title compound contains one mol-ecule rather than two indep...

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 rin...

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.
متن کاملN-(2-Formylphenyl)-4-toluenesulfonamide: a second monoclinic polymorph
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 8...
