Structure of Pentaamminechlorocobalt(Ⅲ) Tetrachloropalladate(Ⅲ) (Co(NH_3)_5Cl)(PdCl_4)

摘要

The structure of the (Co(NH_3)_5Cl)(PdCl_4) complex, obtained by reacting pentaamminechlorocobalt(Ⅲ) chloride with potassium tetrachloropalladate(II), was determined. Unit cell parameters are a = 16.344(6) A, b = 9.424(3) A, c = 7.968(2) A; V= 1227.2(7) A~3; Z = 4; space group Pna2_1; GOOF = 0.65; R_hkl = 0.024. The coordination polyhedron of the (PdCl_4)~(2-) complex anion is a planar square. These complex anions form columns parallel to the (001) direction. The Cl-Cl contact between the atoms of different anions is shortened. A system of N-H···Cl hydrogen bonds exists in the crystals.
