I am Looking for a green color molecule less than 3 angstrom in size...

I have found Cr2O3 but its greater than 3.5 angstrom... so anything smaller will do the job :)

 I don't have size lists, but several metal chlorides and oxides and disulphides are green, try Vanadium and Titanium for the less exotic ones. If you can do some size research I can make a green list.
 Thanks studiot, Actually I didn't find any size database either... so I am making guesses by assuming the molecules are cubic in shape; so its length = CubeRoot (Mass/Volume) :p I checked it with water & it wasn't bad; Mass of molecule= 3x10^-23 gm Density = 1 gm/cm^3 hence V= m/D = 3x10^-23 cm^3 taking the cuberoot = 3.1x10^-8 cm = 3.1 Angstom The actual value is 2.8 Angstrom on its longest side!

I have bond length tables.
Of course you need the bond angles then.
