Abstract

Mononuclear complexes [ZnL(NO3)2] 1 and [ZnLCl2]·CH3CN 2 are prepared for the first time by the interaction of 6-ferrocenyl-2,2′-bipyridine (L) with zinc(II) salts. The structure of crystal phases is determined by XRD, and it is shown that the nature of the anion ( $\text{NO}_{3}^{-}$ or Cl–) is essential for determining the central atom′s coordination environment. In 1 (space group P21/c), the 5+1 coordination environment is described as a distorted trigonal prism. In 2 (space group $P\bar{1}$ ), the geometry is intermediate between tetrahedral and vacant trigonal bipyramidal.
