A lanthanide-tellurium heterometal encapsulated sandwich-type heteropolyoxoniobate with a 3D pcu-type hydrogen-bonded network. | LitMetric

AI Article Synopsis

  • A novel sandwich-type heteropolyoxoniobate cluster, [Eu(HO)TeNbO(OH)], has been created by integrating a lanthanide cation and tellurite anions into polyoxoniobate.
  • This cluster, referred to as {EuTeNb}, is significant as it is the first known instance of lanthanide-incorporated telluroniobate featuring unique Eu-Te heterometal cations.
  • The compound forms a 3D supramolecular framework due to N-H⋯O hydrogen bonds and displays properties like moderate proton conduction and the ability to adsorb water vapor.

Article Abstract

A rare sandwich-type heteropolyoxoniobate cluster, [Eu(HO)TeNbO(OH)] {EuTeNb}, has been isolated by simultaneously incorporating a lanthanide cation and tellurite anions into polyoxoniobate. The {EuTeNb} cluster represents the first example of lanthanide-incorporated telluroniobate with unprecedented Eu-Te heterometal cations in the sandwiched sites. The N-H⋯O hydrogen bonds link the copper-amine complexes and {EuTeNb} polyoxoanions into a 3D supramolecular framework 1 with pcu topology. Furthermore, compound 1 exhibits moderate proton conduction and water vapor adsorption properties.
