A solvothermal reaction of Co2O3, CoSO4, pyridine-3,5-dicarboxylic acid, and H2O2 in an aqueous MeCN solution yielded a three-dimensional coordination framework [Co3(OH)(pdc)3]·H2O (1) (pdc = pyridine-3,5-dicarboxylate). Compound 1 shows an unprecedented (3,9)-connected (42.6)3(46.621.89) topology in which hydroxycentered mixed-valence Co3(OH)(CO2)6 clusters act as nine-connected nodes of a tricapped trigonal prism, and pdc groups act as three-connected nodes of trigonal geometry.
