Description
Summary:The first example of a coordination polymer with a triply charged metal ion is obtained based on the conformationally mobile bridging ligand 1,4-diazabicyclo[2.2.2]octane N,N′-dioxide (odabco). Its structure is characterized by single crystal X-ray diffraction. The compound has the formula [La(odabco) 3 ]Cl 3 · x H 2 O ( 1 ) with a variable hydration number and is composed of six-coordinated octahedral La 3+ sites. The 3D cationic coordination lattice of 1 has a primitive cubic ( pcu ) topology and contains isolated voids with a total specific volume of 28% filled with chloride anions and water molecules. The compound is characterized by powder XRD and elemental analysis. The absence of absorption maxima in the visible and UV ranges up to 270 nm is shown by diffuse reflectance spectroscopy for 1 .
