The actually observed 1,3-distance, d(XX) is given (within 1% error) by 2CR(X)/F-S, where F-S (= 2-1.41(00)(+/-)) is shown to be an ab initio quantity with no adjustable parameter, no dependence on actual M-X distance or bond order and with 2CR(X) depending only on whether M is an atom of an insulating element (2CR(X) =d(XX)(00)) or whether M is metallic (2CR(X) = 1.1d(XX)(00)). This is illustrated for gas-phase MX2 compounds.</p>10agas-phase10amolecular geometry10aMX2 compounds10atensegrity1 aGanguly, Parthasarathy  uhttps://library.ncl.res.in/content/molecular-geometry-molecular-tensegrity-case-study-gas-phase-mx2-compounds-0
