چکیده
In the title compound, C(12)H(17)N(2)O(5)P, the phospho-nate group is almost orthogonal to both the ethyl groups, with a dihedral angle of 83.75 (11)°. In the crystal, mol-ecules are linked into centrosymmetric dimers via pairs of O-H⋯O hydrogen bonds with an R(2) (2)(20) graph-set motif. The crystal structure is further consolidated by weak C-H⋯π inter-actions.

The asymmetric unit of the title cocrystal, C(12)H(10)N(4)·2C(7)H(6)O(2), comprises a single mol-ecule of benzoic acid and one half-mol-ecule of 2-pyridine-aldazine situated about a centre of inversion. The carboxyl group is coplanar with the benzene ring to which it is connected [O-C-C-C = -172.47 (12)°] and similarly, the 2-pyridine-aldazine mol-ecule is planar (r.m.s. deviation of the 16 non...

In the title co-crystal, C(12)H(10)N(4)·2C(7)H(6)O(2), the complete 4-pyridine-aldazine mol-ecule is generated by a crystallographic centre of inversion. In the crystal, mol-ecules are connected into a three component aggregate via O-H⋯N hydrogen bonds. As both the benzoic acid [O-C-C-C torsion angle = 174.8 (2)°] and 4-pyridine-aldazine (r.m.s. deviation of the 16 non-H atoms = 0.041 Å) mol-ec...

The asymmetric unit of title co-crystal, C14H16N4S2 (2+)·2C7H3N2O6 (-)·4C7H4N2O6, comprises a centrosymmetric dipyridinium dication, a 2,6-di-nitro-benzoate anion and two independent 2,6-di-nitro-benzoic acid mol-ecules. The pyridin-ium rings are each approximately perpendicular to the central di-thio-amide unit [dihedral angle = 80.67 (12)°]. The carboxyl-ate/carb-oxy-lic acid groups are appro...

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 ...
