Magnet brickwork: A two‐dimensional molecule‐based metamagnet is obtained by the reaction of Co II ions and the tetra ‐bidentate {Cu 2 (mpba) 2 } 4− moiety. The Co II ions act as cement between {Cu 2 (mpba) 2 } units to form a brick‐wall assembly (see picture). The strong Co II anisotropy and weak interplanar interactions lead to a metamagnetic transition and glassy behavior.
