Abstract
Some kinds of {RuII-NO+}-type complexes containing a diethylenetriamine ligand were prepared from hydrous RuX3·NO (X = Cl or Br) and diethylenetriamine. Among them, the crystal and molecular structures for trans-mer-[RuCl2(dien)NO]PF6 (1) and mer-[RuBr3(Hdien)NO]Br·H2O (2) (dien = diethylenetriamine) were determined by X-ray diffraction. The crystal of 1 was monoclinic, space group P21/a with a = 21.296(4), b = 6.602(2), c = 10.079(2) A, β = 97.12(2)°, Z = 4, and final R = 0.0307, and the crystal of 2 was orthorhombic, space group P212121 with a = 11.988(4), b = 17.234(9), c = 7.141(2) A, Z = 4, and final R = 0.0825. In 1, the two chloro ligands were in the trans arrangement and the dien was in the meridional arrangement as a tridentate ligand. In 2, the three bromo ligands were in the meridionalarrangement with the Hdien coordinated to the ruthenium through one terminal and central nitrogen atoms as a bidentate ligand, and the remaining uncoordinated terminal moiety was –NH3+. The trans-strengthening eff...
