Druding, Leonard F.; Shupack, Saul I. published the article 《Separation of square planar complexes by thin layer chromatography》. Keywords: PYRIDINE COMPLEX CHROMATOG; THIN LAYER CHROMATOG; CHROMATOG SEPN SQUARE PLANAR COMPLEX; PLATINUM COMPLEX CHROMATOG; PALLADIUM COMPLEX CHROMATOG; SEPN SQUARE PLANAR COMPLEX.They researched the compound: cis-Dichlorobis(pyridine)platinum(II)( cas:15227-42-6 ).Application In Synthesis of cis-Dichlorobis(pyridine)platinum(II). Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:15227-42-6) here.
Uncharged sq. planar Pt and Pd complexes were separated by using plates with a 100 μ coating of silica gel bound by poly(vinyl alc.) and activated for 30 min. at 115°. The solvent was HCCl3 containing 3 drops Me2SO per 100 ml. Typical Rf values are given. Separation of cis- and trans-Ptpy2X2 (X = Cl, Br) was particularly successful, while cis- and trans-Pt(NH3)2Cl2 could not be separated The mechanism of separation appears to be via surface adsorption. Layer thickness, activation conditions, and solvent travel time are therefore very critical
