Abstract
A DTA study of thermal decomposition of (NH4)2[Ru(NO)Cl5] in helium atmosphere has been carried out, a synthetic procedure for preparation of the trans-diammine complex mer-[Ru(NO)(NH3)2Cl3] (I) with yield ~70% has been developed. On re-crystallization of I from aqueous solution a trans-aquanitroso complex [Ru(NO)(NH3)2Cl2(H2O)]Cl⋅H2O (II) has been isolated. The structures of the compounds have been determined by single crystal X-ray diffraction: space group Pbcn, a = 6.607(1) Å, b = 11.255(2) Å, c = 9.878(2) Å (I) and space group Ima2, a = 8.3032(3) Å, b = 8.0890(2) Å, c = 15.9192(5) Å (II).
