Techniques for CollectorsMalachite and HCL Reactoin

Cu2(CO3)2(OH)2 + HCL → CO2 + H2O + Cu2CL ???
Any help would be greatly appreciated.

Cu2(CO3)(OH)2 + 4 HCl -> CO2 + 3 H2O + 2 CuCl2

The formula for Malachite I took directly from Simon and Schuster's Guide to Rocks and Minerals. I was able to find a complete formula showing the reaction of iron with the cloride ions.
2Fe +Cu2CO3(OH)2 +4 HCL -→ CO2(g) + 3H2O(aq) + 2FeCl2(aq) + 2Cu(s)

what is the structural formula of malachite?
Are the atoms all connected like in HCl or are they ionic, like NaCl?

A simplified formula would be Cu2CH2O5. The partitioning of the oxygen in the carbonate and hydroxl groups connotates the structural grouping of the anion elements. (the carbonate is actually the carbon surrounded by three oxygens, and doesn't have O-O bonding).
The exact positions of the atoms in the unit cell can be found by searching for malachite at:
