| Abstract: | Two-dimensional complexes of Cd(cpoa)(o-pbim)]
n
(1) and {Cd3(cpoa)3(o-pbim)2] · 2H2O}
n
(2) (cpoa2− = 4-carboxyphenoxy acetate, o-pbim = 2-(2-pyridyl)benzimidazole) are synthesized under hydrothermal condition. Single crystal
X-ray diffraction analysis shows that complex 1 contains a mono-nuclear unit, whereas complex 2 contains a trinuclear unit. The structural difference of 1 and 2 can be attributed to the various coordination modes of asymmetrically semi-flexible cpoa2− ligand. The luminescent properties of these two compounds are also investigated. |
