AB  - The title compound, [Ni(C20H17N3OP)(N-3)], is the first complex with a semicarbazide-based ligand having a P atom as one of the donors. The influence of the P atom on the deformation of the coordination geometry of the Ni-II ion is evident but less expressed than in the cases of complexes with analogous seleno-and thiosemicarbazide ligands. The torsion angles involving the two bonds formed by the P atom within the six-membered chelate ring have the largest values [C-P-Ni-N = 24.3 (2)degrees and C-C-P-Ni = -24.2 (4)degrees], suggesting that the P atom considerably influences the conformation of the ring. Two types of N-H center dot center dot center dot N hydrogen bond connect the complex units into chains.

AB  - The title compound, [Cu(C9H13N5O2)(CH4O)](NO3)(2), consists of square-planar cationic complex units where the Cu-II centre is coordinated by an N, N, O-tridentate pyridoxal aminoguanidine Schiff base adduct and a methanol molecule. The tridentate ligand is a zwitterion exhibiting an almost planar conformation. The dihedral angles between the mean planes of the pyridoxal ring and the six-and five-membered chelate rings are all less than 2.0 degrees. The charge on the complex cation is neutralized by two nitrate counter-ions. Extensive N -H center dot center dot center dot O and C -H center dot center dot center dot O hydrogen bonding connects these ionic species and leads to the formation of layers. The pyridoxal hydroxy groups are the only fragments that deviate significantly from the flat layer structure; these groups are involved in O-H center dot center dot center dot O hydrogen bonding, connecting the layers into a three-dimensional crystal structure.
