Bis[[aqua­(1H-imidazo[4,5-f][1,10]phenanthroline-κ²N⁶,N⁷)cadmium]bis­(μ-pyridine-2,3-dicarboxyl­ato)-κ³N,O²:O³;κ³O³:N,O²]

In the title compound, [Cd₂(C₇H₃NO₄)₂(C₁₃H₈N₄)₂(H₂O)₂], the Cd^II ion is six-coordinated by two N atoms from a 1H-imidazo[4,5-f][1,10]phenanthroline (IP) ligand, one N atom and one O atom from a pyridine-2,3-dicarboxyl­ate (pdc) ligand, one O atom from another pdc ligand and one water mol­ecule in a distorted octa­hedral geometry. Two Cd^II ions are bridged by a pair of pdc ligands, forming a centrosymmetric dinuclear structure. Neighboring dinuclear units are linked by the coordinated water mol­ecules through O—H...N and O—H...O hydrogen bonds, forming a layer parallel to (011). The layers are further linked into a three-dimensional network through N—H...O hydrogen bonds. π–π inter­actions between the IP ligands further stabilize the supra­molecular structure [centroid–centroid distances = 3.579 (3), 3.686 (3), 3.710 (3), 3.766 (3) and 3.841 (3) Å].

(Ethano­lato-κO)[N′-(3-meth­oxy-2-oxidobenzyl­idene-κO²)benzo­hydrazidato-κ²N′,O]oxidovanadium(V)

In the title complex, [V(C₁₅H₁₂N₂O₄)(C₂H₅O)O], the V^V ion is coordinated by an oxide O atom, an ethano­late anion and two O atoms and one N atom from the tridentate benzo­hydrazidate dianion in a distorted square-pyramidal geometry; the V atom is displaced by 0.4748 (8) Å from the basal plane towards the axial oxide O atom. An intra­molecular O—H...N hydrogen bond occurs in the benzohydrazidate ligand. Weak inter­molecular C—H...O hydrogen bonding is present in the crystal.
