Two isomers of [RuCl(2mqn)<SUB>2</SUB>(NO)] (2mqn=2-methyl-8-quinolinolate ion) were isolated and their crystal structures were determined by X-ray diffraction. In both the isomers, the Cl atom lies cis to the NO group and the O atom of one of the quinolinolato ligands lies trans to the NO group. One of the two isomers, (<B>1</B>), is in cis(O,O) and trans(N,N) configuration for the two quinolinolato ligands, another, (<B>2</B>), being in cis(O,O) and cis(N,N). Crystal data: <B>1</B>, space group <I>P</I>2<SUB>1</SUB>⁄<I>c</I> (monoclinic), <I>a</I>=7.412(1), <I>b</I>=27.241(6), <I>c</I>=9.752(1) Å, β=105.49(1)°; <B>2</B>, space group <I>P</I>2<SUB>1</SUB>⁄<I>c</I> (monoclinic), <I>a</I>=7.157(2), <I>b</I>=20.205(4), <I>c</I>=13.359(3) Å, β=107.70(2)°. The final <I>R</I> values for <B>1</B> and <B>2</B> are 0.044 for non-hydrogen atoms and 0.037 for all the atoms, respectively. The coordination geometries of <B>1</B> and <B>2</B> are distorted octahedron. The interatomic distances are qualitatively discussed on the basis of π- and σ-bonding abilities of the NO group, the Cl, and the coordinating atoms, N and O, of the quinolinolato ligands.
