Synthesis and structural properties of a 2D Zn(II) dodecahydroxy-closo-dodecaborate coordination polymer.
Ready AD, Becwar SM, Jung D, Kallistova A, Schueller E, Anderson KP, Kubena R, Seshadri R, Chmelka BF, Spokoyny AM. Ready AD, et al. Dalton Trans. 2022 Aug 2;51(30):11547-11557. doi: 10.1039/d2dt01292h. Dalton Trans. 2022. PMID: 35842939
In this work, we discuss the synthesis and characterization of a 2D coordination polymer composed of a dianionic perhydroxylated boron cluster, [B(12)(OH)(12)(2-)], coordinated to Zn(II)-the first example of a transition metal-coordinated [B(12)(OH)(12)](2-) …
