Reaction
of 2,3,6,7,10,11-hexaaminotriphenylene
with Ni<sup>2+</sup> in aqueous NH<sub>3</sub> solution under aerobic
conditions produces Ni<sub>3</sub>(HITP)<sub>2</sub> (HITP =
2,3,6,7,10,11-hexaiminotriphenylene), a new
two-dimensional metal–organic framework (MOF). The new material
can be isolated as a highly conductive black powder or dark blue-violet
films. Two-probe and van der Pauw electrical measurements reveal bulk
(pellet) and surface (film) conductivity values of 2 and 40 S·cm<sup>–1</sup>, respectively, both records for MOFs and among the
best for any coordination polymer
