Synthesis and Crystal Structure of Dibromido{2-[(4-tert-butylmethylphenyl) iminomethyl]pyridine-κ<Superscript>2</Superscript><Emphasis Type="Italic">N</Emphasis>,<Emphasis Type="Italic">N'}</Emphasis>Zinc

The title compound [Zn(dip)Br₂] was synthesized using the Schiff base bidentate ligand (E)-4-tert-butyl-N-(pyridine-2-ylmethylene)benzeneamine (dip) and zinc(II) bromide salts. It has been characterized by elemental analysis, X-ray diffraction, and optical spectroscopy. The X-ray diffraction analysis demonstrates that in this structure, the zinc(II) ion is located on an inversion center and exhibits a ZnN₂Br₂ tetrahedral geometry. In this structure the dip ligand is coordinated with zinc(II) ion in a cyclic-bidentate fashion forming a five-membered metallocyclic ring. The compound crystallizes in the monoclinic sp. gr. P2₁/m with a = 9.2700(13) Å, b = 7.6128(11) Å, c = 12.3880(17) Å, and β = 97.021(3)°.

The centrosymmetric dinuclear title complex [Hg₂Cl₄(dip)₂] was synthesized using the Schiff base bidentate ligand (E)-4-ethyl-N-(pyridine-2-ylmethylene)benzeneamine (dip) and mercury(II) chloride salts. It has been characterized by elemental analysis, X-ray diffraction, and UV-Visible and infrared spectroscopic techniques. The X-ray analysis shows that the title compound crystallizes in the monoclinic sp. gr. P2₁/n, Z = 2 with a = 7.8233(17) Å, b = 15.178(3) Å, c = 12.559(3) Å, β = 97.021(3)°. The Hg(II) ion has a distorted trigonal–bipyramidal coordination environment formed by the bischelating N-heterocyclic ligands, two bridging Cl atoms and one terminal Cl atom.
