OK, a new update:
The cobalt derivative CoCP seemed very promising at first. Low sensitivity (like the others) very high power when heated in Al foil, non-hygroscopic,
sensitive to flame from fuse and DDTs in small amounts with little containment. However, when I did initiation tests, it didn't perform so well. I had
multiple failures from ca. 20 mg loadings on 5mm coloumns of RDX.
I have since turned towards the iron derivative, FeCP. It behaves a little strangely during synthesis, and I suspect that the iron(III) ions that I
have been using are oxidizing the carbohydrazide. The iron(II) that is formed is probably what is precipitating as the energetic complex in the form
of (suprisingly) white, needle shaped crystals. I have only done very preliminary testing, but it seems very powerful indeed. It detonates in
sub-milligram amounts in the open on flame contact. I can't comment on sensitivity yet, but will report when I have new findings.
