Abstract Designing highly conducting metal–organic frameworks (MOFs) is currently a subject of great interest for their potential applications in diverse areas encompassing energy storage and generation. Herein, strategic design which metal–sulfur plane integrated within MOF to achieve high electrical conductivity, successfully demonstrated. The {[Cu 2 (6-Hmna)(6-mn)]·NH 4 } n ( 1 , 6-Hmna = 6-mercaptonicotinic acid, 6-mn 6-mercaptonicotinate), consisting two dimensional (–Cu–S–) plane, synthesized from the reaction Cu(NO 3 ) 6,6′-dithiodinicotinic acid via situ cleavage an S–S bond under hydrothermal conditions. A single crystal found have low activation (6 meV), small bandgap (1.34 eV) highest conductivity (10.96 S cm −1 among MOFs measurements. This approach provides ideal roadmap producing conductive with batteries, thermoelectric, supercapacitors related areas.
