文摘
We are using the coordinating anion tetrakis(imidazolyl)borate to construct new metal-organic framework structures.In this report, we present three alkaline earth metal network solids incorporating this anion. All three compoundshave the same formula, M[B(Im)4]2(H2O)2 (M = Mg, Ca, Sr), and the same coordination environment about themetal. However, the three compounds have different network structures with different degrees of hydrogen bonding;the Mg material forms a two-dimensional network and the Ca and Sr compounds form one-dimensional chains. Inaddition, we present the structure of the protonated anion B(HIm)(Im)3 as a model for the default structure of thisanion and discuss how the conformation of tetrakis(imidazolyl)borate can affect the structure of network solids.
