(4,4) net based on linear trinuclear [Cd3(COO)3] clusters (SBUs1), while 3 presents a rarely binodal (4,6)-connected fsc topological net based on linear trinuclear [Cd3(COO)3] clusters (SBUs1) as four-connected nodes and “chairlike” tetranuclear [Cd4(μ3-OH)2(COO)6] clusters (SBUs2) as six-connected nodes, with the Schläfli symbol of (44·610·8)(44·62). Fluorescence measurements reveal that 2 displays
