The present investigations concerned by structural parameters specially torsion on angles inside unit cell that responsible for monoclinic lattice. Structural investigations via XRD proved that the monoclinic structure phase with C12/C1 space group and lattice parameter a = 11.809(2), b = 8.293(1), c = 9.923(2) A respectively is formed with high quality at elevated temperature 1100°C. A visualized investigations were performed to confirm structure validity and stability at temperature of sintering (1100°C ) . Visualization studies indicated that variations of bond distances between Co1,Co2,P1 and P2 and different six oxygen atoms ( O1 ,O2 , O3 ,O4 ,O5 and O6) inside crystal lattice are responsible for increasing lattice flexibility factor ( by controlling in shrinkage and expansion coefficient ) and consequently increase its bonds stability to break .
