Abstract:

We carried out experimental SQUID and EPR studies together with LSDA + U quantum calculations of the electronic spectra and spin density distribution for dimeric crystals {[}(L)(2)Cu(2)Cl(2)(H(2)O)], where L = 6-phenyl-3-(2-pyridyl)-5-trifluoroacetylmethylidene-4,5-dihydro-1,2,4-tr iazine. We found experimentally and confirmed numerically that mu(eff) (T), T < 52 K, and M (B), T = 2 K, are affected by intradimer spin polarization of the 1,2,4-triazine fragment and interstack exchange interactions. The interplay between pi-stacking and Cu1-Cu1\# antiferromagnetic coupling causes a structure instability which ends up by spontaneous destruction of the crystal at 2 K under influence of DC and AC magnetic fields.
