 Title    Synthesen und Kristallstrukturen von PPh4[RuCl4(NO)(NSCl)] und (PPh4)2[RuCl4(NS)]2-4C H 2CI2 Syntheses and Crystal Structures of PPh4[RuCl4(NO)(NSCl)] and (PPh4)2[RuCl4(NS)]2-4 CH 2C12  
 Abstract    By reaction o f trithiazylchloride, (NSC1)3, with PPh4[RuCl4(N O)]2 in dichlorom ethane the thiazylchloridenitrosyl com plex PPh4[RuCl4(N O)(N SC l)] is obtained; its vacuum pyrolysis at 2 0 0 -2 2 0 °C yields the thionitrosyl com plex (PPh4)2[RuCl4(N S)]2 which crystallizes from C H 2C12 solution with four m olecules o f CH 2C12. Both com pounds were charaterized by their IR spectra and by X-ray crystal structure determ inations. Crystal data: PPh4[RuCl4(N O)(N S C l)], m on o­ clinic, space group P 2 xln, Z = 4, a = 982.6, b = 1700.0, c = 1772.3 pm , ß = 104.79° (2548 observed reflexions, R = 0.046); (PPh4)2[RuCl4(N S)]2-4 C H 2C12, triclinic, P I , Z = 1, a = 952.9, b = 1380.0, c — 1458.5 pm , a — 112.91, ß = 106.67, y = 92.61° (3760 observed reflexions, R = 0.053). In the [RuCl4(N O)(N S C l)]e ion the nitrosyl and thiazyl chloride ligands occupy e x ­ positions; bond lengths indicate double bonds in the linear Ru = N -0 group, while the NSC1 m olecule is attached by a donor-acceptor interaction R u -N = S -C l , although with a rather short Ru —N bond o f 198 pm (N = S 144 pm, S —Cl 213 pm). The centrosymm etric [RuC14(N S)]220 ions have chloro bridges and NS ligands in axial positions; the nearly linear R u = N = S group has bond lengths R u = N 175 pm and N = S 147 pm.
