✦ Synopsis
C~1~ symmetry and C–H···O and C**–H···O hydrogen‐bond donor/acceptor ability** of the title phase π‐donor are expressed by a glide plane (a ± c/2 repetition), uniform stacks, and a band structure quarter‐filled with holes. Conductivity and spin susceptibility data demonstrate strong Mott localization at ambient pressure which is weakened at high pressure. These results show that the 1/4‐Umklapp scattering channel is efficient enough for localization in 1D, strongly correlated electron systems.
