# How can I identify and draw the geometric isomers for the isomers of [Ni(CN)_2Cl_2]^(2-)?

Well, you can do this with ease if you know that this $N {i}^{2 +}$ complex is square planar. You have 4 ligands to distribute around the sides of the square, the cyanide ligands can be cis (on the same side as each other) or trans. I couldn't find a good picture to illustrate the isomers; find a textbook on inorganic chemistry.
