If one takes the simple crystalline state -- with the extreme case in which the lattice points are occupied by only two kinds of oppositely charged atoms such as Na+ Cl - -- as the perfect opposite of the living condition, then one has -- (although being restlessly "dead") a certain formal approximation in the inorganic complex-compounds which may be multiply complexified and, for instance in the heteropolyacids, may form "uni-molecules" of considerable size. We have placed "uni-molecules" between quotation marks, for taking the mentioned forms to be true molecules will meet with much more opposition, and indeed is less legitimate than are the organismic uni-molecules. They themselves [i.e. the inorganic molecules], even in their monomerous form, are considerably close to crystals. They are, each of them, taken to be a molecular compound [i.e. a compound, first of all, between molecules], because they often could not be formulated along the line of chief valences (at least in the old sense), although a real binding between molecules, a binding, over and above the most common intermolecular or Van der Waals forces as a base, surely would result in a larger new molecule.
