This is carbon monoxide on copper, and if you count in everything then
unfortunately your bit density/volume is really lousy.
Compare that to http://what-if.xkcd.com/31/

I doubt you can squeeze more than 1 bit/nm^3 in a 3d
lattice of addressable sites. That gives you around 10^21 bits/cm^3.
That's the kind of density you need for Avogardo scale computing
(somewhere between 1 mole bits/liter or at least 1 m^3,
or about one 19" rack, if one still thinks in ancient units).
