Abstract Single crystals of the new compound Ba2KZn3(B3O6)(B6O13) were obtained by using a B2O3 flux technique; they crystallize in an as yet unknown structure type. X-ray investigations led to the space group Ci1-P1̄ (Nr.2) with lattice parameters a = 705.2(2), b = 712.5(2), c = 1880.3(6), a = 93.43(3)°, β = 90.72(2)°, γ = 119.57(2)°, Z = 2. The structure contains (B3O6)3--rings and a new discrete (B6O13)8- anion, which is composed of two BO4 and two B2O5 units. Zn2+ is tetrahedrally coordinated by oxygen and two out of three tenfold coordinated Ba-sites are statistically occupied by Ba2+ and K+.
