In the title mol-ecule, C(8)H(9)N(3)O(4), the amide group is involved in the formation of an intra-molecular N-H⋯N hydrogen bond. In the crystal, mol-ecules related by translation along the a axis are linked into chains via weak inter-molecular C-H⋯O inter-actions.

A series of mono-cationic dinuclear have been synthesized using ((pyridi picolinamide (L2) ligands: [(h6-arene C5Me5)2M2(m-L1)Cl3]þ (M 1⁄4 Rh, 4 p-PrC6H4Me, 7; C6Me6, 8), [(h-C5Me isolated as their hexafluorophosphate IR spectroscopy.

The title compound, [Na2(C6H5N2O2)2(C6H6N2O2)4], is a centrosymmetric coordination dimer based on the sodium(I) salt of N-hy-droxy-picolinamide. The mol-ecule has an {Na2O6(μ-O)2} core with two bridging carbonyl O atoms and two hydroxamate O atoms of two mono-deprotonated residues of N-hy-droxy-picolinamide, while two neutral N-hy-droxy-picolinamide mol-ecules are coordinated in a monodentate m...

The title compound, [Ni(N(3))(2)(C(6)H(6)N(2)O)(2)], was obtained as the first crystalline product from the reaction of Ni(NO(3))(2)·6H(2)O, picolinamide and NaN(3) in aqueous media. After a few days in the mother liquor, crystals of the cis isomer transformed into the trans isomer [Đaković & Popović (2007 ▶). Acta Cryst. C63, m507-m509]. The Ni atom exhibits a distorted octa-hedral environment...
