The iodine, despite its high coordination, turned out <strong>not<\/strong> to be hypervalent, with its (s\/p) valence shell not exceeding eight electrons (and its d-shell still with 10, and the 6s\/6p shells largely unoccupied). Instead, the 14 valence electrons (7 from H, 7 from iodine) fled to the H&#8230;H regions. Well, perhaps H is special in its ability to absorb electrons into the H&#8230;H regions. So how about I(CN)<sub>7<\/sub>? (the species has not hitherto been reported in the literature according to CAS). The cyano group is often described as a <a href=\"http:\/\/en.wikipedia.org\/wiki\/Pseudohalogen\" target=\"_blank\">pseudohalide<\/a>, but the advantage of its use here is that it is about the same electronegativity as I itself, and hence the I-C bond is more likely to be covalent (than for example an I-F bond). As noted in the earlier blog, if the potentially hypervalent atom is very ionic, it can be difficult to know whether the electrons are truly associated with that atom, or whether they are in fact in lone pairs associated with the other electronegative atom (e.g. F). It is also important to avoid large substituents, otherwise steric interactions will cause problems around the equator.<\/p>\n<div id=\"attachment_2621\" style=\"width: 222px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-2621\" class=\"size-full wp-image-2621\" title=\"ICN7\" onclick=\"jmolInitialize('..\/Jmol\/');jmolSetAppletColor('yellow');jmolApplet([600,600],'load wp-content\/uploads\/2010\/10\/ICN7.log;frame 37;set measurementUnits Angstroms;delay 5;vectors on;vectors 4;vectors scale 5.0; color vectors purple; vibration 15;animation mode loop;');\" src=\"http:\/\/www.ch.ic.ac.uk\/rzepa\/blog\/wp-content\/uploads\/2010\/10\/ICN7.jpg\" alt=\"\" width=\"212\" height=\"252\" \/><p id=\"caption-attachment-2621\" class=\"wp-caption-text\">I(CN)7.

The C-I bond lengths range from 2.20\u00c5 (equatorial) to 2.10\u00c5 (axial); the Wiberg bond orders for these are respectively 0.482 and 0.609. The total bond orders are 3.94 (iodine), 3.91 (carbon) and 3.14 (nitrogen). The total carbon bond order for e.g. atom <strong>2<\/strong> is made up of 0.482 to I, 2.939 to N, 0.110 to C6, C7, 0.049 to C5, C8 and 0.040 to C3, C4. As with IH<sub>7<\/sub>, the erstwhile hypervalent iodine electrons have in fact departed from that atom, and taken up residence in the C&#8230;C regions. The NBO analysis confirms the electrons as originating from an effective iodine core (28), explicit I,C,N cores (46), 69.3 valence and 0.7 Rydberg (outer shell) electrons. The molecular orbitals are shown in <a href=\"http:\/\/www.ch.ic.ac.uk\/rzepa\/blog\/?p=2647\" target=\"_blank\">this post<\/a>.<\/p>\n<p>Finally, for good measure, ELF analysis (on top of an effective core of 28) integrates to an outer core of 17.78 on iodine and a valence shell which includes 17.5 electrons distributed in seven explicit C-I disynaptic basins of ~2.5 electrons each. These 17.5 electrons can be considered as originating from ~10 (non-bonding?) electrons corresponding to the filled iodine 5d-shell, and ~7.5 shared bonding electrons in the iodine 5s\/5p shell (the ELF procedure cannot distinguish between the 5d and 5s\/5p electrons). There is no indication from these integrations that the iodine valence shells are expanded (<em>i.e<\/em>. from 10 for the 5d or from 8 for the 5s\/5p).<\/p>\n<p>As with IH<sub>7<\/sub>, this molecule shows absolutely no evidence of being hypervalent! So, if hypervalency is to survive as a concept, the hunt must surely be on for one unambiguous, as yet to be found, example of the phenomenon in the main group.<\/p>\n<!-- kcite active, but no citations found -->\n<\/div> <!-- kcite-section 2619 -->","protected":false},"excerpt":{"rendered":"<p>In the last post, IH7 was examined to see if it might exhibit true hypervalency.
