6)-connected ant-type 3 employs heterometallic trinuclear Cd2Ba(COO)4} clusters as SBUs. The structures of these three compounds indicate that the SBUs play an important role in the construction of MOFs. Moreover, the thermal stabilities and solid-state photoluminescent properties of these three compounds have also been investigated.
