The author has found in recent years that bond lengths are exact sums of the radii of adjacent atoms and or ions, where the ions have Golden ratio based radii. This work was prompted by the exciting observation last year of the Golden ratio in the magnetic properties of cobalt niobate. It is shown here that in cobalt and zinc niobates, cobalt, zinc and oxygen ions have Golden ratio based ionic radii, whereas in lead niobate, all atoms have covalent radii. Also, the angles at the single bond oxygen anion and atom are close to 108 0 , as in a pentagon. The experimental finding 1-3 of the E8 symmetry in the magnetic properties of cobalt niobate, CoNb 2 O 6 provoked the author's interest to look into the atomic structures of niobates. It was found 4-7 in recent years that the Golden sections of the covalent bond lengths d(AA) between two atoms of the same kind are sums of the radii of Pauling's ionic resonance forms 8 , which are the cations and anions of the atom (A), i.e., d(AA) = d(AA)/φ + d(AA)/φ 2 , where φ (= 5 1/2 + 1)/2 is the Golden ratio. In particular, the inter-ionic distances in all alkali halides (M + X-) were shown to be exact sums of the Golden ratio based ionic radii, d(M +) = d(MM)/φ 2 and d(X-) = d(XX)/φ. On this basis, the bond lengths d(AB) in molecules between any two atoms and or ions were found to be sums of the atomic and or ionic radii 4-7 .
