Synthesis and Single Crystal Structure Description of Two New Polyoxometalate–Melamine Hybrids
Abstract Two new organic–inorganic hybrid compounds based on Keggin-type polyoxometalates and melaminium cations, namely (C3N6H7)3[PW12O40]·6H2O (1) and (C3N6H7)4[SiW12O40]·6H2O (2) have been synthesized at room temperature by a solvent diffusion...
Crystal Structure of New POM-Based Organic-Inorganic Hybrid
The title POM-based organic-inorganic hybrid compound consists of one PMo12O40
3– polyoxoanion, three symmetrically
independent glycinium cations and five solvated H2O molecules; several N–H·O and O–H·O hydrogen bonds between...
Determination of optimal pH and temperature for urease enzyme activity immobilized on a new organic-inorganic hybrid matrix
The enzyme urease (urea hydrolase.EC:3.5.1.5) cleavages urea to ammonium and carbon di-oxide.
Immobilization of enzyme is mostly used in technology nowadays. For example: immobilized urease is used
for ...
