@Canageek Nitrate ligands also bound to the UO2++? also, I assume there is another pair of uranyl cations bound to the other pair of cyano ligands?
@Canageek what's the molecular weight of this polymer? is it a soluble oligomer or is it enormous?
@mona Effectively the size of the crystal, it doesn't have a defined MW in the same way an organic polymer does, and only exists in the crystal state.
@Canageek ah, got you. I was vaguely imagining some kind of precipitated high-molecular-weight complex, like a "Prussian blue".
@Canageek Also, do you know if other cyanometallates form similar coordination compounds with uranyl cation? I'd be curious indeed if Ni(CN)4-- made a planar polymer.
@mona Almost certainly. There have been examples of thorium with Pt(CN)4, for example, but I'm the only one who has looked at this and I've not tried with other cyanometallates (yet).
@mona Yeah, think more like a sodium chloride crystal.
This is exactly like prussian blue, actually, that is the example our group uses when explaining it.
@Canageek Are the nitrate ligands subject to exchange?
@mona They usually just do salt metathesis and leave. Do you want a copy of the paper?
@Canageek sure, if that's all right!
@mona Turns out since I was on the cover it is open access: http://pubs.rsc.org/en/content/articlepdf/2017/dt/c7dt00942a
@mona Exactly. So it forms a continuing chain.
