A hydrothermal reaction between mixed linkers and mixed metals, alkaline earth 4MgCO 3 ·Mg(OH) 2 ·5H 2 O and 3d Ni(CH 3 COO 3 ) 2 ·4H 2 O, resulted in a unique metal-organic framework of SNNU-99 that was impressively isolated and structurally characterized. SNNU-99 was constructed from an unprecedented decanuclear Mg/Ni-based secondary building unit and represents the first (3,10)-connected 3-period net. Alternatively, SNNU-99 can be described through an unusual kgd layer pillared through 2-connected linkers. Due to its specifically structural feature, SNNU-99 has demonstrated selective CO 2 adsorption over N 2 . The first (3,10)-connected MOF of SNNU-99 featuring an unprecedented decanuclear Mg/Ni-based SBU was impressively isolated and structurally characterized.
