HW 9C.9

[AChoudhry_1L]

With the help of Table 9C.1, determine the coordination number of the metal ion in each of the following complexes: (a) [NiCl4]2–; (b) [Ag(NH3)2]+; (c) [PtCl2(en)2]2+; (d) [Cr(edta)]-

How would we determine the coordination numbers for c and d?

[Zaynab Hashm 2I]

to help you figure those out, you must know that;

in c (en) = bidentate
in d (edta) = hexadentate

*count as binding sites to get the coordination number

[CynthiaLy4F]

en would be a bidentate because it binds to the central atom at two points because of the lone pairs on two of its nitrogens. edta would be a hexadentate and bind to the central atom at six points.
