Some Transformations of trans-Tetrapyridine Complexes of Nitrosoruthenium: Crystal Structures of [Ru(NO)Py4(OH)](PF6)2 ⋅ (CH3)2CO and [H5O2]2[Ru(NO)Py4Cl]Cl4

详细

The slow evaporation of an acetone solution containing trans-[Ru(NO)Py₄(OH)]²⁺ cations and hexafluorophosphate anions results in the crystallization of trans-[Ru(NO)Py₄(OH)](PF₆)₂ ⋅ (CH₃)₂CO (I). The reactions of trans‑[Ru(NO)Py₄(OH)]Cl₂ ⋅ H₂O with solutions of chloric or hydrochloric acid followed by the evaporation of the reaction solutions at ambient temperature afford trans-[Ru(NO)Py₄(H₂O)](ClO₄)₃ (II) or [H₅O₂]₂[Ru(NO)Py₄Cl]Cl₄ (III), respectively. The obtained chloride complex III is unstable and at ambient temperature eliminates hydrogen chloride to transform into trans-[Ru(NO)Py₄Cl]Cl₂ ⋅ 4H₂O (IV). The crystal structures of compounds I and III are determined by X-ray structure analysis (CIF files ССDC nos. 1421042 (I) and 1421041 (III)).
