A magnesium–lithium heterometallic coordination network

A three-dimensional magnesium–lithium coordination network, Mg2Li(BTC) (HBTC)(DMF)2, (1) (BTC = 1,3,5-benzenetricarboxylate; DMF = N,N-dimethylformamide), the first example of a mixed-metal Mg–Li coordination network, is synthesized using solvothermal techniques. Structural characterization was completed using single crystal x-ray techniques while thermal properties and surface area measurements were conducted by thermogravimetric and BET analysis, respectively.

Graphical AbstractThe three-dimensional magnesium–lithium coordination network, Mg2Li(BTC) (HBTC)(DMF)2 is first example of a mixed-metal Mg–Li coordination network and provides an excellent starting point for the targeting of new mixed lightweight metal MOFs.Figure optionsDownload as PowerPoint slideResearch Highlights
