Chemical Bonds: Metals:
“But metallurgists found no vertexial bonds in metals. Fifty years later came x-ray diffraction. In 1932 Linus Pauling made x-ray diffraction analysis of the structures of many metals. All of the metals thus far x-ray diffraction analyzed, 35 years later, have proven to be tetrahedronally coordinated but in a great variety of nonvertexial associations. Instead of the tetrahedra being coordinated vertex to vertex in the metallic assemblages, their centers of gravity are usually congruently coordinate. Sometimes the metals are also mid-edge coordinated. Those are the metals.”
