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 Ci 1-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+.
通过使用B2O3熔剂技术,获得了新化合物Ba2KZn3(B3O6)(B6O13)的单晶,它们结晶在尚未知的结构类型中。X射线研究得出空间群Ci1-P1̄(Nr.2),晶胞参数为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。该结构包含(B3O6)3-环和一个由两个BO4和两个B2O5单元组成的新离散(B6O13)8-阴离子。Zn2+由氧四面体配位,而三个十面体配位的Ba位点中的两个被Ba2+和K+统计占据。
