Synthesis and X-ray crystal structures of heteroleptic zinc amidinate complexes
The synthesis of heteroleptic zinc amidinate complexes is reported. Reactions of LZnI [L = t -BuC(NDipp) 2 ; Dipp = 2,6- i -Pr 2 -C 6 H 3 ] with diisopropylcarbodiimide ( i -PrN) 2 C yielded the Lewis acid-base adduct LZn(I)-N( i -Pr)CN( i -Pr) 1 . In addition, the synthesis of LZnN(SiMe 3 ) 2 2 and its reaction with ( i -PrN) 2 C, which occurred with formation of the heteroleptic amidinate-guanidinate complex LZnL ′ 3 [L ′ = (Me 3 Si) 2 NC(N i -Pr) 2 ], is reported. Compounds 1 – 3 were characterized by
nuclear magnetic resonance ( 1 H, 13 C) and infrared spectroscopy,
elemental analysis, and single crystal X-ray diffraction ( 1 and 2 ), respectively.
