Chemistry - Solid State Question with Solution | TestHub

The solid state structure of molybdophosphate is based on a cuboctahedron (shown below). A molybdenum atom lies at each vertex of the cuboctahedron, and these are joined by oxygen atoms with every edge of the cuboctahedron being bridged by an oxygen atom. A further oxygen atom is joined to every vertex. A single phosphate unit lies at the centre of the structure with each of its four oxygen atoms coordinating to three molybdenum atoms. The combined number of oxygen atoms and molybdenum atoms in such a cuboctahedron is $\_\_\_\_$ .
