The one dimensional chain structures of vanadyl glycolate and vanadyl acetate†
Abstract
The O bond of 1.684(7)
Å and a short trans V-O bond of 2.131(7)
Å, and by bridging acetate groups. The vanadium atoms interact along the ⋯V
O⋯V
O⋯ chain giving one-dimensional antiferromagnetic behavior. In contrast in the glycolate, the apical V
O bond is shorter, 1.58(1)
Å, and the square pyramids share edges in a two up–two down fashion to give chains of formula VO(OCH2CH2O). Magnetic susceptibility of vanadyl glycolate is consistent with an isolated spin dimers model.
