A copper complex crystallising in a CCP lattice with a cell edge of $0.4518 \mathrm{nm}$ has been revealed by employing $\mathrm{X}$-ray diffraction studies. The density of a copper complex is found to be $7.62 \mathrm{g}{ \mathrm{cm}}^{-3}.$ The molar mass of copper complex is$\underline{ }$ ${\mathrm{gmol}}^{-1}$
