BeSiOH
BeSiOH is a chemical notation used in inorganic and materials chemistry to denote a beryllium–silicon–oxygen–hydrogen containing species. It does not refer to a single well-characterized compound; rather, BeSiOH is used in various contexts to describe Be–Si–O–H clusters or surface adsorbates in silicate chemistry and gas-phase studies. Depending on the study, BeSiOH may represent a neutral cluster with a Be–O–Si framework and a terminal hydroxyl group, or a fragment of a larger Be–Si–O network where Si is tetrahedrally coordinated to oxygens and Be is bound to one or more oxygens, bearing a hydrogen.
Structures are typically envisioned as Be–O–Si linkages with one or more hydroxyl groups (–OH) attached to Be
BeSiOH is primarily discussed in theoretical or experimental studies of low-coordinate silicate chemistry, cluster chemistry, and
Safety: Be compounds are highly toxic and require appropriate handling and containment.
