Reaction of the Schiff base ligand (R)-2-(pyrrol-2-ylmethyleneamino)-2′-methoxy-6,6′-dimethyl-1,1′-biphenyl with tetrakis(dimethylamido)vanadium in toluene gives the mononuclear VIVtitle complex, [V(C2H6N)2(C20H19N2O)2]·C7H8, which was isolated as red crystals. The VIVcation is coordinated by two monoanionic bidentate Schiff base ligands and two N atoms of two dimethylamide anions in a VN6distorted octahedral coordination geometry, in which two N atoms from the dimethylamide anions are placed in acis-configuration.

In the title complex, [Mn(C7H2N2O7)(C10H8N2)] n , the MnII atom has a distorted octahedral coordination geometry, defined by two N atoms from the 2,2′-bipyridine ligand and four O atoms from two 3,5-dinitrosalicylate dianions. One carboxylate O atom acts as a bridge between adjacent metal centres to form a one-dimensional chain. The Mn...Mn distance is 4.315 (6) Å. The crystal packing is stabilized by intermolecular C—H...O hydrogen interactions.

Reaction of gallium(III) nitrate with (E)-1-[1-(2-pyridyl)ethylidene]thiosemicarbazide (petc) afforded the title complex, [Ga(C8H9N4S)2]NO3. The title complex contains one GaIII cation and two enol-form petc anions, accompanied by one charge-balancing disordered nitrate anion. The petc is in the enol form, coordinating to the GaIII centre via one S atom and two N atoms. Thus, the GaIII centre assumes a distorted octahedral coordination geometry.
