More detail analysis reveals that in one cluster node, only a single CF3COO -unit is attached, along with five associated linker molecules. Conversely, in the adjacent cluster node, two CF3COO -units are attached in opposite directions, accompanied by four linker molecules (Fig. ). These two CF3COO -units attach via a µ1 bridging mode. The linker molecules are attached through Cu-N bond where the four linker molecules are linked through mutual diagonal position whereas the additional linker molecule positioned opposite to the CF3COO -unit (Fig. ). The presence of these bidentate linker molecules causes the cluster nodes to act as repeating units in the overall structure. However, the diagonally attached four linker molecules are connected to the adjacent cluster nodes, the additional linker molecule, positioned opposite to the CF3COO -unit, does not connect to any other cluster node but facilitates structural growth through interlayer stacking. Due to the linear nature of the linker molecules and their coordination to the cluster nodes, the extended structure forms a rhombohedral framework in a two-dimensional (2D) plane (Fig. ). Each cluster node is separated by ~15.315 Å along the axis, while the linker molecules themselves have a length of 11.378 Å. These 2D layers are stacked in an AB stacking fashion through noncovalent interactions, with a separation of approximately 9.726 Å between each layer.
