Dichloridobis(2-phenyl­pyridine-κN)zinc(II)

In the title compound, [ZnCl₂(C₁₁H₉N)₂], the Zn²⁺ cation lies on a twofold axis and is coordinated by two Cl⁻ anions and the N atoms of two 2-phenyl­pyridine ligands, forming a ZnN₂Cl₂ polyhedron with a slightly distorted tetra­hedral coordination geometry. The dihedral angle between the phenyl ring and the metal-bound pyridine ring is 50.3 (4)° for each 2-phenyl­pyridine ligand. This arranges the phenyl ring from one ligand in the complex above the pyridine ring of the other resulting in an intra­molecular π–π inter­action, with a centroid–centroid distance of 3.6796 (17) Å. Weak C—H...Cl hydrogen bonds stabilize the crystal packing, linking mol­ecules into chains along the c axis.

Bis(4,4′′-difluoro-1,1′:3′,1′′-terphenyl-2′-carboxyl­ato-κO)bis­(3,5-dimethyl-1H-pyrazole-κN²)manganese(II)

In the title compound, [Mn(C₁₉H₁₁F₂O₂)₂(C₅H₈N₂)₂], the Mn²⁺ cation is coordinated by the N atoms of two 3,5-dimethyl­pyrazole ligands and carboxyl­ate O atoms from two 4,4′′-difluoro-1,1′:3′,1′′-terphenyl-2′-carboxyl­ato ligands, forming an MnN₂O₂ polyhedron with a slightly distorted tetra­hedral coordination geometry. Two intra­molecular hydrogen bonds are observed between the carboxyl­ate and pyrazole ligands. The combined influence of the sterically hindered carboxyl­ate ligands and the intra­molecular hydrogen-bonding inter­actions stabilizes the title compound with a low coordination number of four. In the crystal, weak C—H...F and C—H...O hydrogen bonds are observed.
