In a subsequent modification, we replaced the tppa linker with another tridentate ligand, tpbt, to investigate its effect on the synthesis of the Cu CAM. This adjustment triggered a rearrangement of the Cu(I) atoms, resulting in the formation of a Cu7 cluster node (Fig. ). This cluster node rearrangement is also influenced by the electronic environment of the linker molecules, which promotes the formation of larger cluster nodes with the most negatively charged linker configuration (Fig. ). However, the negative zeta potential value may not be sufficient here to form the Cu10 cluster node, possibly due to the coordination site specificity of the linker molecules in the system. This new node consisted of four S t Bu -ligands, two CF3COO -ligands, and six tpbt linker molecules (Fig. ). The additional Cu(I) atom incorporation to the cluster node opens up the possibilities to coordinating with the auxiliary ligands and thus CF3COO -ligands were attached to the node. Similar to the previous framework, this Cu7 cluster node also forms a 3D network. However, in this case, each node connects to six neighboring nodes, resulting in a distinct structural arrangement (Fig. ). Here the inter-node distance was found to be 19.097 Å, reflecting the expanded framework geometry.
