Single crystals of a new compound with the empirical formula Cu2CoB2O6
were obtained by using a B2O3 flux technique. X-ray single crystal te
chnique led to a new structure type. Cu2CoB2O6 crystallizes monoclinic
, space group C2h5-P2(1)/c (No. 14); a = 3.2250(6); b = 14.847(1); c =
9.1171(6) angstrom; beta = 93.67-degrees; Z = 4. All metal sites are
octahedrally coordinated and form a two dimensional framework consisti
ng of edge sharing octahedra ribbons. In addition one observes isolate
d B2O5-units and oxygen which is not coordinated to boron. The far rel
ation to the crystal structure of the mineral Warwickite is illustrate
