Abstract

Three new metal-organic framework materials [Mg ₃(LH) ₂(EtOH) ₂(H ₂O)]·(EtOH) _4.5(H ₂O) _0.25 (IMP-13Mg), [Co ₃(LH) ₂(EtOH) ₂(H ₂O)]·(EtOH) ₃ (IMP-13Co), and [Ca ₃(LH) ₂(EtOH) ₄]·(EtOH) ₆ (IMP-14) have been prepared from the treatment of silanetetrabenzoic acid (L-H ₄) with Mg ^II, Co ^II, and Ca ^II salts respectively. In all cases the silanetetrabenzoic acid has been triply deprotonated and the resultant carboxylate groups assemble with trinuclear metal-based nodes to give (3,6)-connected kgd-type two-dimensional layers. These layers are then extended into the third dimension by coordination of the metal nodes by carboxylic acid groups in adjacent layers. In the case of IMP-13Mg/Co, only alternate L-H connectors and metal nodes are involved in these interlayer interactions, leaving some acid groups free within the structure. However, in IMP-14 all L-H connectors and metal nodes participate in interlayer bonding.
