| Abstract
| - The synthesis and characterization of two members of a family of porous magnetic materials isdescribed. The structures of Co4(SO4)(OH)6(C2N2H8)0.5·3H2O and Co4(SO4)(OH)6(C6N2H12)0.5·H2O and theirthermal stability can be tailored via the choice of organic pillar. The interactions between the pillaring agentand the compositionally complex inorganic layer are discussed. The influences of two pillaring agents i.e., theflexible ethylenediamine and the relatively rigid 1,4-diazabicyclo[2,2,2]octane, on thermal stability, rigidityupon guest loss, and magnetic behavior of the pillared solids are compared. The magnetism of the pillaredlayered cobalt hydroxides is complex due to the influences of multiple metal sites, inter- and intralayer exchange,spin−orbit coupling, and geometrical frustration. The wide variety of potential pillars, oxyanions, and possiblemetal substitutions at the octahedral and tetrahedral sites offers the possibility of tailoring the magnetic andporous properties of these materials.
