The d10-metal-oxo clusters connected by the asymmetric tricarboxylate and linear neutral ligands give rise to two novel high-connected MOFs. They feature the highest (3,16)- and (3,8)-connected three-dimensional frameworks based on cube-like octanuclear [Zn8(μ2-OH)4(CO2)12] clusters and butterfly-like tetranuclear [Cd4(μ3-OH)2(CO2)6] clusters as the secondary building units, respectively.
