Abstract:
The tripodal ligand 1,3,5-(CH3)3C6[CH2OCH2C(pz)3]3 (L1, pz=pyrazolyl ring) reacts with AgBF4 to yield ([L12Ag3(CH3CN)](BF4)3).(CH3CN)4, an inclusion complex in which the encapsulated acetonitrile cannot escape the triangular cage unit in either the solid or solution phase. The analogous hexatopic ligand C6[CH2OCH2C(pz)3]6 forms a 2-dimensional polymer composed of similar triangular cage units, again with the encapsulation of one acetonitrile molecule, linked by the additional tris(pyrazolyl)methane units. In contrast, the complex formed with L1 and Cd2+ has a double, open cage structure holding two diethyl ether molecules.

Complexation Equilibria: Factors Influencing Stability of Complexes
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...
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...
