چکیده

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-H atoms = 0.017 Å). In the crystal, mol-ecules are connected into a non-planar three-mol-ecule aggregate [dihedral angle between the benzene and pyridyl ring connected by the hydrogen bond = 61.30 (7)°] with a twisted Z-shape. Layers of 2-pyridine-aldazine mol-ecules in the ab plane are sandwiched by benzoic acid mol-ecules being connected by O-H⋯N and C-H⋯O inter-actions, the latter involving the carbonyl O atom so that each benzoic acid mol-ecule links three different 2-pyridine-aldazine mol-ecules. Inter-digitated layers stack along the c axis.

In the crystal of the title 1:1 adduct, C(8)H(7)ClO(2)·C(12)H(10)N(4), the components are linked by an O-H⋯N hydrogen bond between the carb-oxy-lic acid and one of the pyridine N atoms. In the acid, the carb-oxy-lic acid group is approximately normal to [dihedral angle = 72.9 (2)°] but twisted with respect to the plane through the benzene ring [C-C-C-O torsion angle = 25.4 (5)°]. The base is ro...

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 title compound, [Ir(η(5)-C5Me5)Cl(C18H14ClN3)]B(C6H5)4, is chiral at the metal center and crystallizes as a racemate. In the cation, the hydrazinyl-idene-pyridine ligand is N,N-coordinated through the N-pyridyl and N-hydrazinyl-idene groups forming a five-membered metallacycle. An intra-molecular C-H⋯Cl hydrogen bond is observed. In the crystal, centrosymmetrically-related cations are conne...

The cation of the title compound, [Rh(η(5)-C5Me5)Cl(C13H12ClN3)]Cl, adopts a typical piano-stool geometry. The complex is chiral at the metal and crystallizes as a racemate. Upon coordination, the hydrazinyl-idene-pyridine ligand is non-planar, an angle of 54.42 (7)° being observed between the pyridine ring and the aromatic ring of the [2-(4-chloro-phen-yl)hydrazin-1-yl-idene]ethyl group. In th...
