Abstract
We have carried out calculations for the one dimensional quantum Heise nberg antiferromagnet with alternating dimers and four-spin plaquettes . This geometry is the one-dimensional counterpart of the two-dimensio nal structure of the spin gap compound CaV4O9. The properties of the s ystem are discussed in dependence on the competing dimer and plaquette bonds.
