WebApr 10, 2015 · We here present the fourth crystal structure at all of a silicide complex anion in the crystal structure of [K 0.28 Rb 7.72 Si 9 Ni(CO) 2] 2 ·16NH 3, which proves the stability of the transition metal complex in a rigid cation-anion-ammonia network without any further chelating additives. WebThe free ligand and the metal complexes were characterized using a number of spectroscopic methods. The crystal structure of [ZnLBr]ClO 4 showed that the Zn(II) ion was in a distorted square pyramidal environment. The crystal structure of [CuL](ClO 4) 2 showed that the Cu(II
