We present X-ray and optical spectroscopic observations of twelve galaxygroups and clusters identified within the XMM Large-Scale Structure (LSS)survey. Groups and clusters are selected as extended X-ray sources from a 3.5deg2 XMM image mosaic above a flux limit 8e-15 ergs/s/cm2 in the [0.5-2] keVenergy band. Deep BVRI images and multi-object spectroscopy confirm each sourceas a galaxy concentration located within the redshift interval 0.29
