Coordination number of diamond structure
WebThe coordination number of each carbon is 4. Thus, diamond is a giant three-dimensional molecule in which each carbon–carbon bond length is 154 pm, forming strong covalent bonds with each bond angle measuring 109.5°. Diamond has an isometric structure, which implies that the carbon atoms are bonded in the same way in all directions. General ... WebDec 5, 2024 · A type of ionic crystal structure in which the cations have an expanded face-centred cubic arrangement with the anions occupying both types of tetrahedral hole. The cations have a coordination number of 8 and the anions have a coordination number of 4. Examples of compounds with this structure are CaF2, BaCl2, and PbO2.
