ABSTRACT: A novel dinuclear complex
[Co2(atr)3(mal)2(H2O)2]·4H2O(1) (atr = 4-amino-1,2,4-triazole and mal = malonic acid) containing mixed
N and O-donor atoms has been prepared and structurally characterized. The
structure is made up of the symmetrically 1, 2, 4-triazole bridged [Co2(atr)3(mal)2(H2O)2]
moiety and four lattice water molecules. The single crystal X-ray analysis
reveals that the complex has a distorted octahedral structure. Magnetic susceptibility
measurements reveals that antiferromagnetic interactions exists between the
high spin Co(II) ions within the dinuclear unit.
