(C2H8N)2[Be3(HPO3)4]: a low-density beryllium phosphite with large 16-membered rings and helical channels†
Abstract
A beryllium-containing open framework, which is analogous to that found in the structure of (C2H8N)2[M3(HPO3)4] (M = Zn, Co), has a low density and represents the first example of a Be containing inorganic solid with 16-membered rings.
