摘要

The substituted bis (pyrazolyl) methane ligands RCH (3, 5-Me2pz) 2 (R= SiMe3 (1), CH2Ph (2), G1 (3), G2 (4), and G3 (5); Gn= Fréchet-type dendritic wedges of generation n) have been prepared starting from H2C (3, 5-Me2pz) 2. Reaction of these didentate ligands with [NiBr2 (DME)] is a straightforward procedure that allows the synthesis of the nickel (II) complexes [NiBr2 {RCH (3, 5-Me2pz) 2}](6–10). The molecular structure of compound 7 ( ...
