      <dc:description>Monomeric [Co(SDZ)2phen] (1) and [Co(SDZ)(bq)Cl] (2) complexes (SDZ = sulfadiazine, phen = 1,10-phenanthroline,&#xd;
and bq = 2,2’-biquinoline) have been synthesized and characterized. X-ray diffraction studies&#xd;
indicate that SDZ acts as a bidentate ligand coordinating through the sulfonamide and the pyrimidine N&#xd;
atoms in both compounds. In complex 1, the coordination sphere consists of two SDZ ligands and a bischelating&#xd;
phen ligand, giving rise to a CoN6 coordination sphere. On the other hand, 2 has a CoN4Cl core,&#xd;
with two N-atoms from SDZ and two from the bq ligand. Both compounds have been studied by dc and ac&#xd;
magnetometry and shown to display slow magnetic relaxation under an optimum external dc field (1 kOe) at&#xd;
low temperatures. Moreover, compound 2 displays long range magnetic ordering provided by spin-canted&#xd;
antiferromagnetism, which has been characterized by further field-dependent magnetic susceptibility&#xd;
measurements, FC/ZFC curves, hysteresis loops and frequency-independent ac curves. The signs of the calculated&#xd;
D parameters, positive in 1 and negative in 2, have been rationalized according to the two lowest-lying&#xd;
transitions in the orbital energy diagrams derived from ab initio ligand field theory (AILFT). In a subsequent&#xd;
attempt to reveal the possible hidden zero-field SMM behaviour, Ni(II)-based 3 and Co(II)-doped Ni(II)-based&#xd;
(with a Ni :Co ratio of 0.9 : 0.1) heterometallic compound 2Ni were synthesized.</dc:description>
