“…Dinuclear copper(II) complexes in which the metals are bridged by only a single hydroxo, alkoxo or phenoxo-oxygen group are relatively rare, 34,42,[45][46][47][48][49][50] and a none straightforward correlation between structure and magnetism has been developed. However, similar compounds with double (OR) groups have been extensively studied.…”

“…As a matter of fact, doubly Hbridged copper dimers can exhibit experimental coupling constants between limiting values of À4 cm À1 [35] and À94 cm À1 [36]. Different intermediate values have also been reported [22,37] as well as density functional calculations on these dimers [29]. As compared to values up to À94 cm À1 , the observed exchange is weaker in the studied compound.…”

Three new multicomponent crystals 1a–1c of Zn(II), Mn(II), and Co(II), respectively, were synthesized by the reaction of 2,6-bis(hydroxymethyl)pyridine, the respective metal salts, and sodium benzoate in a 1:1:2 ratio. One component of these multicomponent crystals 1a–1c is the dicationic 2,6-bis(hydroxymethyl)pyridine metal complex and the other component is the dianionic tetrabenzoate complex of the same metal. The complexes were fully characterized by single-crystal X-ray structure determination. The X-ray structure of these compounds 1a–1c reveals the formation of 1D supramolecular chain parallel to the crystallographic b axis via H-bonding interactions between the dicationic and dianionic parts of the respective compound. The Mn(II) ( 1b ) and Co(II) ( 1c ) complexes show antiferromagnetic coupling between the two associated metal centers via the H-bonding interaction pathway. All the three compounds 1a–1c were tested as heterogeneous catalytic systems for the successful conversion of epoxides to cyclic carbonates in solvent-free condition under approximately 10 bar of pressure of CO 2 and temperature ranging between 60 and 80 °C along with tetrabutyl ammonium bromide acting as a cocatalyst. All the three compounds 1a–1c were found to have turnover number more than 1000 for the respective epoxides except for the conversion of cyclohexene oxide to cyclohexene carbonate.
