X-Ray crystal structure of the organic conductor from 2,2′-bi-(2,4-diselenabicyclo[3.3.0]octylidene) and 7,7,8,8-tetracyano-p-quinodimethane (HMTSF–TCNQ)

Abstract
The X-ray crystal structure of the organic conductor HMTSF–TCNQ consists of separate stacks of radical cations and radical anions coupled so as to make this the most two-dimensional member of the TTF–TCNQ family of organic metals.
