I am just wondering, can I make a metalorganic or organometallic complex of copper and limonene/terpinene/phellandrene in the form of lime oil? If so, what is the formula of the complex formed? I tried the reaction with lime oil in iPrOH, and a copper sulfate solution. The result was a blue crystalline solid. What are the crystals? I'd like to know.

$\begingroup$ By the way, the compound is an opaque blue solid, and I used iPrOH to dissolve and extract the terpenes, as well as to wash the crystals. $\endgroup$– user102173Commented Dec 14, 2020 at 0:20

$\begingroup$ The terpenes in the oil, I mean. It's poorly soluble in water, and insoluble in iPrOH. $\endgroup$– user102173Commented Dec 14, 2020 at 0:27

1$\begingroup$ Most of the evidence you present, together with solubility data from Wikipedia, seems consistent with just precipitating the copper sulfate. Note that because of spectrochemical effects, we would expect the complex to change color if organic ligands were to displace water. $\endgroup$– Oscar LanziCommented Dec 14, 2020 at 1:30

2$\begingroup$ Yes there is nothing in terpenes to coordinate with copper ion. You got copper sulfate again. $\endgroup$– ACRCommented Dec 14, 2020 at 1:44

For the record, after M. Farook's agreement I am making my comment an answer.
