  • In this paper we report the synthesis and characterization of some new derivatives of the isomers cis- (1) and trans-RuCl2(DMSO)4 (6) (DMSO=dimethyl sulfoxide) with monodentate nitrogen donor ligands (L) such as NH3, imidazole (Im) and benzimidazole (BzIm): cis,fac,-RuCl2(DMSO)3(L) (L=NH3 (2) Im (3)); cis,cis,cis-RuCl2(DMSO)2(Im)2 (4); fac-[Ru(Im)3Cl(DMSO)2]PF6 (5); trans,cis,cis-RuCl2(DMSO)2(L)2 (L=NH3 (7), Im (8), BzIm (9)); trans,-RuCl2(DMSO)3(Im) (10). All complexes have exclusively S-bonded DMSOs. Their chemical behavior in aqueous solution is also described. The crystal structures of cis,fac-RuCl2(DMSO)3(NH3) (2) and trans,cis,cis-RuCl2(DMSO)2(NH3)2·H2O (7) were determined by three dimensional X-ray analyses. Crystal data: 2, a=9.103(2), b=12.568(2), c=13.375(6) Å, β=96.52(2)°, monoclinic, space group P21/n, Z=4; 7, a=8.507(4), b=11.331(4), c=14.071(4) Å, β=90.99(1)°, monoclinic, space group P21c, Z=4. Least-squares refinement based on 4045 (2) and 3682 (7) reflections converged to R=0.026 and 0.030 for 2 and 7, respectively. In 2, the three DMSOs have RuS bond distances of 2.2774(6) and 2.2458(5) Å (trans to Cl), and 2.2877(5) Å (trans to N). The RuCl bond distances are 2.4178(6) and 2.4411(6) Å (trans to S), while the RuN (trans to S) bond length is 2.151(2) Å. In 7, the trans RuCl bond distances are 2.4030(7) and 2.4125(7) Å, while the RuS (trans to N) bond distances are 2.2350(6) and 2.2469(6) Å, and the RuN (trans to S) 2.142(2) and 2.156(2) Å.
