چکیده
Complexes [MII(2-pytz)Cl2] (M(II) = Pt, Pd; 2-pytz 2-(tetrazol-1-yl)pyridine) were synthesised via direct interaction of the corresponding metal chlorides (K2PtCl4 or PdCl2) with under ambient conditions. RuCl3 does not react reflux in protic media, while N, N-dimethylformamide presence LiCl, decomposition tetrazole cycle occurred leading to formation Ru(III)-coordinated N-dimethyl-N ′-(pyridin-2-yl)formimidamide derivative Li[RuIII(Py — N =C NMe2)2Cl2]. The complex [Ru(2-pytz)(DMSO)3Cl2] ⋅ MeOH, where DMSO is dimethyl sulfoxide, was by reacting a specially prepared precursor cis-[Ru(DMSO)4Cl2] methanol [Ru(2-pytz)(DMSO)2Cl2] ethanol resulting complexes characterised elemental analyses, electrospray ionisation mass-spectrometry detection positive and negative ions, infrared spectroscopy, 1H 13C nuclear magnetic resonance (NMR) simultaneous thermal analysis. structures [Pd(2-pytz)Cl2] MeOH investigated single-crystal X-ray In former, shows N,N-chelating coordination pyridine ring N2 atoms. latter, coordinates as monodentate ligand N4 atom. According NMR spectroscopy data, [Ru(2-pytz)(DMSO)2Cl2], N-chelating
