    Metal–organic frameworks (MOFs) are a class of compounds consisting of metal ions or clusters coordinated to organic ligands to form one-, two-, or three-dimensional structures. They are a subclass of coordination polymers, with the special feature that they are often organic ligands included are sometimes referred to as "struts", one example being 1,4-benzenedicarboxylic acid (BDC). Arsenic is a chemical element with symbol As and atomic number Arsenic occurs in many minerals, usually in conjunction with sulfur and metals, and also as a pure elemental c is a can exist in various allotropes, although only the gray form has important use in industry.. The main use of metallic arsenic is for strengthening alloys of copper and especially lead Appearance: metallic grey.
