Alle Reaktionen wurden unter gereinigtem Stickstoff in Standard-Schlenk-Technik durchgefuhrt. Bei den niedrig aufgelosten Massenspektren sind die mjr-Werte des jeweils stirksten Signals im Isotopenmuster angegeben.
triclinic, PT (no. 2), a =15.647(2), h = 22.325(3), c =14.852(4) A, a = 94.91(2), B = 90.17(2), y = 83.53(1)", V = 5136(1) A', Z = 4, pCllcd = 1.463 gcm-', T = 296 K. Instrumentation and software were as noted for 1. The structure was solved by Patterson methods and expanded by using fourier techniques. Hydrogen atoms were included but not refined. Of 18771 data collected (maximum 26 = SO", Mo,., p = 22.52 cm-'), 18033 were unique. The final residuals for 1082 parameters refined against 8078 unique data with I > 30(I) were R = 0.053 and R, = 0.054. Crystallographic data (excluding structure factors) for the structures reported in this paper have been deposited with the Cambridge Crystallographic Data Centre as supplementary publication no.
