 Title    Structure of Chloro(cyclopentadienone)- (cyclopentadienyl)ruthenium and its Cytotoxic Activity  
 Abstract    The structure of R u(cpO)(cp)C l com plex (3), which was precipitated from aqueous solutions of R u(cp)2Cl+PF6' (1), was determined by X-ray crystallographic analysis. The Ru-halogen bond distance was shorter and the dihedral angle be­ tween the rings was larger than the values re­ ported for the corresponding Br analogue, R u(cpO)(cp)Br (4). The com plex 3 (IC50 1 09 /iM) was more cytotoxic than 1 (IC50 163 //M) against mouse sarcoma S I80 cells, but less toxic than 4 (IC50 72 ,/M).

 Title    Inin -Phthalocyanine: Darstellung, Eigenschaften und Kristallstruktur von £-Bis(triphenylphosphin)iminium-as-di(cyanato(N))phthalocyaninato- (2-)indat(III)  
 Abstract    In111 Phthalocyanines: Synthesis, Properties and Crystal Structure of Z?-Bis(triphenylphosphine)iminium c/5-D i(cyanato(N))phthalocyaninato(2-)indate(III) B arbara Aßm ann, A ndreas Franken, [In(Cl)Pc2~] reacts with bis(triphenylphosphine)iminium cyanate ((PNP)OCN) in dichlo-romethane to yield green-blue *(PNP) [In(NCO)2Pc2_] • CH2C12, which crystallizes in the triclinic space group Pi (No. 2) with Z = 2. The two cyanato(N) ligands are in a mutually cis coordination (Z (NNCO-In -N NCO) = 84.2(3)°). The In atom is displaced out of the plane of the four N,.vo atoms towards the two cyanato(N) ligands (d(In-Ct(N,JO)4) = 0.988 A). The average In-N NC0 and In-N,.so bond distances are 2.16(1) and 2.216(8) A, respectively. The NNco-In -NNCO moiety deviates by ~ 4° from the staggered conformation relative to the In-(N,,")4 sceleton. Though the cyanato(N) ligands are essentially linear, there are different In-N -C angles (164.4(9) and 147.1(8)°) probably due to crystal packing effects. The Pc2~ ligand is distorted in an asymmetrically convex manner. The PNP cation adopts the bent conformation (Z(P-N(K)-P) = 143.5(6)°). The cyclic voltammogram shows three electrode processes, which are assigned to the redox pairs: Pc ~/Pc2~ (-0.87 V) < In'/In111 (-0.63 V) < Pc~_ /Pc~ (0.69 V). The UV-VIS-NIR spectra and the vibrational spectra are discussed.
