Abstract:
X-ray diffraction shows that the title cadmium(II) complex, [Cd(2)(C(14)H(20)O(2))(2)(C(5)H(5)N)(6)].2C(5)H(5)N, has a dimeric structure in which two (py)(3)Cd(3,5-di-tert-butylcatecholate) units (py is pyridine) are connected by two bridging O atoms, the coordination of the Cd atoms being distorted octahedral. There are two symmetrically independent dimers in the crystal structure; one is in a general position and the other lies about an inversion centre. In both cases, the bridging Cd-O distances between the Cd-catecholate units [2.224 (2)-2.237 (2) A] are shorter than the bridging Cd-O distances within the catecholate cycle [2.273 (2)-2.281 (2) A]. The Cd-N(py) distances are 2.354 (2)-2.471 (2) A. Besides the main molecules, the crystal also contains pyridine solvate molecules.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
