What is the charge for Hexaminotriphenylene?

Click For Summary

Discussion Overview

The discussion centers around the stability and charge of hexaminotriphenylene (HITP) when substituted with magnesium (Mg) instead of transition metals like chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), rhodium (Rh), osmium (Os), and iridium (Ir). The focus includes theoretical implications and structural considerations related to metal-organic frameworks (MOFs).

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions the stability of HITP when substituting Mg for transition metals, noting the structural differences.
  • Another participant highlights that Mg lacks certain properties that transition metals possess, prompting further inquiry into the implications of this difference.
  • A participant points out that Mg is not a transition element, which may affect its stability in the proposed structure.
  • There is a suggestion that the stability concern is speculative, reflecting uncertainty about the outcome.
  • It is noted that HITP MOFs typically utilize metals that can form square planar configurations, which are not characteristic of magnesium compounds.

Areas of Agreement / Disagreement

Participants express uncertainty regarding the stability of HITP with magnesium, with no consensus reached on whether it would be stable or not.

Contextual Notes

The discussion does not clarify the specific charge of hexaminotriphenylene or the implications of substituting Mg in terms of charge balance. The assumptions regarding stability and structural configurations remain unresolved.

I have seen the structures like X3 (HITP)2 (X = Cr, Mn, Fe, Co, Rh, Os, Ir). Can I replace X with Mg? Will it be stable?

No idea, but one thing definitely asks for attention: what does Mg miss, that all other metals listed have?
 
well, all the other elements are transition elements where as Mg is not.
 
Yep - that makes me doubt stability. But it is just a guess.
 
HITP MOFs are generally formed with metals in a square planar configuration, which isn’t found in magnesium compounds.
