Talk:Potassium nonahydridorhenate

Isoelectronic compounds
How about KOsH9? Or maybe even "iridane" (IrH9)? The latter would especially be intriguing since it would be the transition metal analogue of methane, silane etc, and might be a gas or volatile liquid. It would be zerovalent like methane (since Ir and H have the same electronegativity). Has anyone tried preparing it, or its homologues rhodane and (Kurt) cobane? 173.165.239.237 (talk) 04:21, 3 February 2012 (UTC)

Geometry: text description vs. drawing
The text describes the geometry as tricapped trigonal prismatic, but the figure now in the article is a monocapped square antiprism. The tricapped trigonal prism geometry is sourced to the book by Holleman and Wiberg, and I have just added as a second source the book by Housecroft and Sharpe which agrees. So I am going to remove the figure with the incorrect geometry, and replace it with a figure of the tricapped trigonal prism which I found at Metal ions in aqueous solution. (No, rhenium is not a lanthanide or actinide, but this figure does show the correct geometry). Dirac66 (talk) 00:23, 13 May 2012 (UTC)
