摘要

Complexes 4a and 4b are only soluble in very polar organic solvents such as DMSO or DMF. Complex 4a was characterized by X-ray analysis (Figure 1) and crystallizes in the monoclinic space group P2 1 /c with the Pd center in a square planar enviroment and with unique N−Pd bond lengths of 2.017 and 2.029 Å. These bonds are slightly shorter than in complexes 1 (R = Me, 2.041 and 2.039 Å) and 2 (R = Me, 2.031 and 2.048 Å). ... Figure 1 X-ray structure ...
