  • Title: Magneto-structural correlation in a metamagnetic cobalt(II)-based pillared trilayer motif constructed by mixed pyridyl-type carboxylate ligands.
    Author: Zhou YL, Wu MC, Zeng MH, Liang H.
    Journal: Inorg Chem; 2009 Nov 02; 48(21):10146-50. PubMed ID: 19791760.
    Abstract:
    The first structurally authenticated example of coordinated polymer featuring homometallic pillared-trilayer structure, [Co(3)(ina)(2)(pico)(2)(H(2)O)(2)](n) (1), was built from mixed pyridyl-type monocarboxylates, isonicotinate (ina) and 3-hydroxypicolinate (pico), containing Kagome-type [Co(3)(pico)(2)(H(2)O)(2)](n)(2n+) trilayers. The magnetic phase diagram of 1 shows a metamagnetic transition below 3.2 K, arising from the competing interactions between the antiferromagnetic intralayer couplings in different amplitudes with obviously noncompensated moments versus weak AF interlayer coupling.
