Abstract:
Two new uranyl arsonates, Zn(UO(2))(PhAsO(3))(2)L·H(2)O [L = 1,10-phenanthroline (1) and 2,2'-bipyridine (2)], have been synthesized by hydrothermal reactions of phenylarsonic acid, L, and ZnUO(2)(OAc)(4)·7H(2)O. Single-crystal X-ray analyses demonstrate that these two compounds are isostructural and exhibit one-dimensional chains in which U(VI) and Zn(II) cations are directly connected by the yl oxygen atoms and additionally bridged by arsonate groups. Both compounds represent the first examples of uranyl arsonates with heterometallic cation-cation interactions.

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...

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
