N2 - Magnetic properties of ferromagnetic (F) and antiferromagnetic (AF) bond alternating quantum spin chain system, DMACuX3 where X = Cl, Br and DMA = (CH3)2NH2, are reported. The most prominent result is that for Cl-compound we observed the unusual mixed state in which S = 1 and 0 dimers coexist evenly due to frustrated situation in the presence of comparable F and AF couplings. For Br-compound, it is shown from the susceptibility measurements that an AF coupling is dominant and it provides an example of simple dimer-limit.
