  25. Crystal structure analyses of thetransdimers proved to be very difficult. Due to the insolubility of4aand4cno crystals were obtained for the Cu and Zn complexes; likewise we have not yet been able to grow crystals of4d. Brown cubes of4bwere obtained from CHCl3/CH3OH. C74H88N8Ni22CHCl3 triclinic space groupP1 a= 10.286(1) b= 12.812(2) c= 14.775(2) Å α = 104.64(1) β = 108.46(1) γ = 95.66(1)° V= 1752.8(7) Å3; data collection at 126 K with CuKαradiation. The structure solution revealed all atoms including two CHCl3molecules of salvation and clearly showed thetransconfiguration of the connecting double bond. However refinement belowR= 0.19 was not possible due to systematic twinning problems.
  26. Characterization of the NiIIcisandtransdimers:4b: m.p. > 300°C; UV/VIS (CH2Cl2): λmax[nm](ϵ) = 414 (1.599 × 105) 488 (30400) 530 (20740) 566 (22760).1H NMR (300 MHz CDCl3 25°C): δ = 9.50 (s 2H meso) 9.48(s 4H meso) 7.66 (s 2H CH  CH) 3.88 (m 16H CH2) 3.76 (q 8H CH2) 3.37 (m br 8H CH2) 1.83 1.82 (t 12H each CH3) 1.75 (t 12H CH3) 1.02 (t 12H CH3).5b: m.p. > 300°C; UV/VIS (CH2Cl2): λmax[nm](ϵ) = 393 (1.682 × 105) 435 (12190) 568 (14650).1H NMR (300 MHz CDCI3 25°C): δ = 9.30 9.05 (s 2H each mesoand CH  CH) 8.06 (s 4H meso) 4.03 3.84 3.75 3.57 3.47 2.89 (m 4H each CH2) 2.60 (s 8H CH2) 1.83 (m 12H CH3) 1.43–1.53 (m 24H CH3) 0.67 (t 12H CH3). Thecisandtransisomers can easily be separated based on solubility properties.

Data collection on a Siemens R3m/V diffractometer at 130 K with MoKαradiation (λ = 0.71073 Å) and a graphite monochromator; crystal size: 0.52 × 0.32 × 0.21 mm.
