The targeted synthesis of new extended modular frameworks exhibiting specific properties is
a principal challenge of modern chemistry research.[1–3] Many inorganic frameworks [4, 5]
and metal–organic frameworks (MOFs)[6, 7] have been reported, but the fine manipulation of
their electronic properties remains challenging.[8] One such approach could be the
development of molecular alloys, analogous to metal alloys, yet this idea has rarely been
applied, and three dimensional (3D) framework alloys based upon molecular building …
