CCUK-18

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Hg2+2N(I,Cl,Br).H2O
Colour:
deep red
Most likely the I analogue of mosesite. Associated with CCUK-10, but may also be isolated. Crystal (up to ~0.3 mm) groups may show growth structures along one axis.

A XRD study showed advanced streaking, suggesting an inhomogenous strain of the structure, with a possibility of a short-range ordering.
