Abstract

The synthesis and characterization of {[Co₅(INA)₃(HCOO)₇(DMF)(H₂O)]·2DMF·4H₂O}_∞ (INA^– = the anion of isonicotinic acid) denoted as Co5-INA·2DMF·4H₂O is reported. The compound was isolated from the reaction of Co(NO₃)₂·6H₂O with HINA in the presence of HCOOH in N,N-dimethylformamide (DMF) at 100 °C. It exhibits a rigid 3-D porous structure based on Co₅ repeating units which are linked through carboxylate ligands (from HCOO^– and INA^–) to form an infinite rod-shaped secondary building unit (SBU). The rods are connected through isonicotinate ligands to produce a unique (3,3,4,4,4-coordinated) 5-nodal 3D network with point symbol (4.5.6.7².9)(4.5.6².7.8)(4.5.7)₂(5.6².7³). Gas sorption studies revealed that Co5-INA displays a microporous structure with BET area 264.5 m² g^–1 and CO₂ uptake of 1.96/1.29 mmol·g^–1 at 273/298 K (1 bar), respectively. Magnetism studies revealed that Co5-INA displays spin canting behavior with a spin glass relaxation process at ca. 5.0 K.
