Please do not adjust margins additional four Cu(I) atoms, forming a middle layer. This middle layer is stabilized by two extra S t Bu -ligands and two CF3COO - ligands, providing further protection to the structure and balancing the overall contributory charge of the additional Cu(I). Anyway, again the arrangement forms a rhombohedral 2D framework where each cluster node is separated by ~15.315 Å along the axis. Each 2D layers were further stacked in AB pattern through non-covalent interaction by maintain a separating distance of ~7.291 Å. The absence of additional linker molecules in this structure, compared to previous results, leads to a shorter interlayer distance than observed in the earlier structure.
