We report on the microscopic model of the recently synthesizedone-dimensional quantum magnet (NO)Cu(NO3)3. Applying density functional theoryband structure calculations, we obtain a leading antiferromagnetic exchangecoupling J ~ 200 K, which runs via NO3 groups forming spin chains along the bdirection. Much weaker couplings J' ~ 2 K link the chains into layers in anon-frustrated manner. Our calculations do not support the earlier conjectureon an anisotropic frustrated square lattice physics in (NO)Cu(NO3)3. Incontrast, the model of uniform spin chains leads to a remarkably good fit ofthe experimental magnetic susceptibility data, although the low-temperaturefeatures of the intrinsic magnetic susceptibility measured by electron spinresonance might call for extension of the model. We outline possibleexperiments to observe the suggested long-range magnetic ordering in(NO)Cu(NO3)3 and briefly compare this compound to other spin-1/2 uniform-chainsystems.
