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.

Bipyridine Ligand

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.

Cation Complex

The anion of the title complex, (C12H14N2)[Co2(C6H4O7)2(H2O)2], is a centrosymmetric edge-shared bioctahedral dimer, in which the two Co atoms are bridged by two alkoxide O atoms of the fully deprotonated citrate ligands. All of the carboxylate groups coordinate in a monodentate fashion to terminal positions, and two water molecules complete the slightly distorted octahedral coordination. The dinuclear cation complex and the dianion are organized around inversion centers. Supramolecular O—H...O and N—H...O interactions stabilize the architecture.
