Abstract
We have studied the electronic structure of the spin-gapped system CsV2O5 by means of an ab initio calculation. Our analysis and a reexamination of the susceptibility data indicate that the behavior of this system is much closer to that of an alternating spin-½ antiferromagnetic chain with significant inter-dimer coupling and weaker interchain couplings than that of isolated dimers as was initially proposed. Comparison to the vanadate family members α'-NaV2O5, γ-LiV2O5, and isostructural compounds like (VO)2P2O7 is discussed.
