Polymorphism in tri-p-tolyl-1,3,5-triazine

6-Chloro-N 2,N 4-di-p-tolyl-1,3,5-triazine-2,4-diamine dimethyl­formamide monosolvate

The title compound, C(17)H(16)ClN(5)·C(3)H(7)NO, was prepared by reaction of p-toluidine with 2,4,6-trichloro-1,3,5-triazine at room temperature. The dihedral angles between the triazine ring and the pendant rings are 3.61 (12) and 53.11 (12)°. An intra-molecular C-H⋯N inter-action occurs. The packing is stabilized by N-H⋯N and N-H⋯O hydrogen bonds and C-H⋯π and π-π [centroid-centroid distance ...

p-Tolyl bis­(p-tolyl­amido)phosphate

In the title compound, C(21)H(23)N(2)O(2)P, the P atom exhibits tetra-hedral coordination; the P-N bond lengths are relatively short [1.6297 (13) and 1.6424 (13) Å]. In the crystal, adjacent mol-ecules are linked by N-H⋯O hydrogen bonds into a zigzag chain running along the c axis.

5-p-Tolyl-1H-tetra­zole

The title compound, C(8)H(8)N(4), possesses crystallographic mirror symmetry, with four C atoms lying on the reflecting plane, which bis-ects the phenyl and tetra-zole rings. It is composed of a planar r.m.s. deviation (0.0012 Å) tetra-zole ring which is nearly coplanar with the benzene ring, the dihedral angle being 2.67 (9)°. In the crystal, symmetry-related mol-ecules are linked by inter-mol...

p-Tolyl bis­(cyclo­hexyl­amido)­phosphinate

The P atom in the title mol-ecule, C(19)H(31)N(2)O(2)P, is in a distorted tetra-hedral configuration with the bond angles in the range 101.48 (10)-118.58 (9)°. The N-H units have a syn orientation with respect to one another. In the crystal, mol-ecules are connected via two different inter-molecular N-H⋯O(P) hydrogen bonds into chains along the a axis in which the O atom of the P=O group acts a...
