Abstract
Reaction of K
2[Ru(NO)Cl
5] with pyridine in aqueous ethanol at pH ~ 7-8 affords a nitrosoruthenium hydroxocomplex mer -[Ru(NO)Py
3Cl(OH)]Cl×1.5H
2O (I), yield ~55 %. The treatment of the hydroxocomplex
I with hydrochloric acid at room temperature gives the aqua complex mer -[Ru(NO)Py
3Cl(H
2O)]Cl
2×2H
2O×0.5HCl (II). The structures of the compounds have been determined by X-ray crystallography:
I - sp. gr.

a = 9.2292(4),
b = 11.7781(4),
c = 17.4915(7) Å, β = 90.9560(10)°,
R = 4.84%;

P -1,
a = 7.3528(9),
b = 11.5793(11),
c = 13.6961(16) Å, α = 84.558(3), β = 87.668(4), γ = 74.146(4)°,
R = 6.22%. Compounds
I and
II have been characterized by powder XRD,
1Н and
13С NMR, as well as IR spectroscopy. Thermal decomposition of compound
II in inert atmosphere has been examined with thermal analysis.
