 Title    Synthesen neuer Fe—P-Käfigverbindungen Syntheses of New Fe —P Cage Compounds  
 Abstract    Four reaction types were used with the aim of obtaining new cage com pounds o f com position F e v(C O)v(P R). with R = M e, Ph. Tol; oxidation of the com pounds Fe2(C O)A(P H R)2. photolysis thereof, reaction betw een RPC12 and Fe2(C O)x:_ , and reaction betw een P —Cl containing iron com plexes and F e(C O)42" . Besides several known products, e.g. F e,(C O)y(P R)2 or F e4(C O)M(P R)2, and derivatives of the Fe2(C O)ft(P R X)2 butterfly type com plexes, the new octabisvalene shaped com pounds Fe4(C O)I2(P R)4 with R = M e. Ph. Tol were obtained and confirm ed by a crystal structure analysis for R = Me. Side products of the oxidative conversions were Fe4(C O),2(P 2M e2) (M e P -C 2H 4-P M e) and Fe4(C O)12(P2T ol2)(P H T ol)2 which can be derived from the octabisvalene type. Side products o f the irradiative conversions were F e,(C O)s(P P h)(P H P h)2 and (C O),F e(a-P H P h)2F e(C O)(Q ,H 8), the structure o f the latter being proved crystallographically.

 Title    Preparation and Reactions of the T etrahedrane Molecule Fe2(CO )6(P-/m -C 4Hg)2  
 Abstract    The F e2P2 tetrahedrane com pound Fe2(CO)f,(P—fBu)2 has been obtained by oxidation of Fe2(C O)A («-PH rB u)2. D ue to its short (206 pm) P —P bond it can be called a diphosphene com ­ plex. In contrast to this the P —P bond is its principal centre o f reactivity: CO , C2H 4, and C2H 2 (with concom itant hydrogenation) are inserted, H 2 and HC1 are added with P —P cleavage, and reductive cleavage occurs with L iB H E t,. The crystal structures of the title com pound and of its CO and C2H 4 insertion products have been determ ined.

The distannoxanes 2a and 2b were found to react very easily with H20 to give the corresponding stan n ols4a and 4b, respectively. In solution (Q ,D ,,or CDC13) the equilibria 2 a/2b + H20 ^ 2 4a/4b were observed ('H N M R). With regard to the system 2a/4a/H20 , this observation is at variance with an earlier report in which the sterically bulky neophyl substituents [C6H 5 (C H 3)2C C H 2] are said to prevent the condensation o f 4a to give 2a. — l b —3b were found to be potent acaricides showing activities similar to those o f their carbon analogues l a —3a (test organisms: adult fem ales o f Tetranychus urticae Koch).

 Title    Borylierte Carbodiimide  
 Abstract    The borylated carbodiim ides 3 a, 3b and 4 can be synthesized by reaction o f the 2-ch loro-l,3,2-diazaborolidines 2 a, 2b with M e3Si —N = C —N —SiM e3 (1) or M e3Si —N = C = N —'Bu respectively. In the reaction of the non cyclic haloboranes R 2BH al (R = Ph, M e, M e2N) 2 c —e with 1 R3B is formed and for R = M e, M e2N polym eric (R BN C N)" is obtained, whilst the spectroscopically identified intermediate products only in the case o f R = Ph can be isolated. The chloroborolane 2 f leads to the polymeric diborylated carbodiim ide 3f, probably due to intermolecular B —N-coordi-nation. H2N —CN forms with 9-BBN the m onoborylated cyanam ide 8 .

 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.

 Title    Über Erdalkalimetallverbindungen des l,l-Dicyanoethylen-2,2-dithiolats, III+ Die Kristallstruktur von SrS2C4N2 * 5 H20  
 Abstract    By reaction of CS2 with m aleonitrile in presence of sodium ethanolate in ethanol, N a2S2C4N 2 is obtained. SrS2C4N2-5 H 20 was synthesized by reaction of Sr(NCS) 2 with N a2S2C4N2 in ethanol. It crystallizes monoclinically, space group P2!/c, with a = 9.201(2), b — 9.990(6), c = 14.605(5) Ä,/3 = 122.3(3)°, Z = 4. The com pound is isotypical with CaS2C4N2-5 H 20 . A structural model based on equivalent metal positions was refined to R -0.057. The crystal structure contains layers of nearly planar [S2C = C (C N)2]2' anions held together by interspersed Sr2+ cations in a tricapped trigonal prismatic surrounding of 6 0 and 3N atoms. The S atom s of the ligand are not included in the coordination sphere of Sr2+ but are involved in several O — H -S hydrogen bonds.
