Abstract
- Abstract: A chiral cluster-based 3D coordination polymer [Co2(ca)(ina)2(H2O)] n (1, ca= d-(+)-camphorate, ina=isonicotinate), containing mixed geometries cobalt(II) dimers as subunit, featuring unique rugate [Co2(ina)2] n 2 n + 2D layers pillared by the ca ligands has been studied. The bridge modes and their intermolecular interactions of the mixed rigid planar ina and flexible bulky ca ligands display an interesting example of shape recognition in packing style of 3D frameworks. The bulky antiferromagnetic behavior of 1, mainly arises from the cooperative magnetic effect of the interdimers arrangement in the chiral 3D network based on the nature of the exchange modes of mixed multi-carboxylate bridges within the mixed geometric Co(II) dimer.
