The use of biomaterials is increasing today and some of the most challenging materials are Calcium compounds. This computational study on calcium compound provides a framework for new materials design and selection for biomaterials used in many areas. All the calculations are carried out on the Gaussian 09.C1 program using Density Functional Theory with the B3LYP hybrid functional method, GEN basis set (we used for phosphorus and oxygen 6-31++G(d,p), for calcium cc-pVDZ). The low HOMO-LUMO gap (1.64 eV for DFT at B3LYP/GEN basis level, 0.93 eV for TD-DFT at B3LYP/GEN basis level) for the molecule explain the chemical reactivity.
