New tridentate 2,6-bis(imino)pyridyl ruthenium(II) complexes, [N3]Ru(H)(Cl)(2,4,6-(CH3)3C6H2NH2) (4) and [N3]Ru(Cl)2(2,4,6-(CH3)3C6H2NH2) (5) ([N3] = 2,6-(2,4,6-(CH3)3C6H2N=CCH3)2C5H3N) have been synthesized and characterized. The crystal of complex 4, which has been grown in benzene/cyclohexane by evaporation at room temperature, was studied by X-ray diffraction. Complex 4 crystallizes in the monoclinic space group C2/c with cell parameters of a = 42.243(4) Å, b = 8.1480(5) Å, c = 23.662(2) Å, β = 117.998(1)°, V = 7191.1(10) Å3, and Z = 8. The molecular structure of 4 shows a six coordinate, pseudo-octahedral geometry with a trans arrangement of hydrogen and chloride ligands. The mesityl ligands are oriented approximately perpendicular to the 2,6-bis(imino)pyridyl ligand plane, and form a pocket surrounding the 2,4,6-trimethyl benzenamine ligand. The coordinated 2,4,6-trimethyl benzenamine (2,4,6-(CH3)3C6H2NH2) is in the cis to chloride and hydride, trans to pyridine ligand, and lies parallel to one of the mesityl rings.
