| ii,5Z n 0,5(6 2 0 5) UI,d C o ^ Z n o ^ I ^ O s) Synthesis and Crystal Structure of the First Zinc Containing Pyroborates Nii.5Z n0.5(B2O 5) and Coj 5Z n0.5(B2O 5) The first zinc containing pyroborates Ni! sZ n ^ B ^ O s) (A) and 5Zn0 5(B 2O 5) (B) were prepared by using a B20 3 flux technique. Single crystals were investigated by X-ray diffrac tion and showed triclinic symmetry, space group C j-P l. The structures are isotypic to C o9(B 20 5) with the lattice parameters (A) « = 331.28(6), 6 = 613.87(11), c = 922.2(2), a = 104.067(11) °, ß = 90.672(13) °, y = 92.413(12) 0 and (B) 0 = 315.89(2), 6 = 612.84(6), c = 927.72(6), a = 104.103(7) °, ß = 91.020(6) °, y = 92.540(7) °, Z = 2. All metal point positions show an octahedral oxygen coordination and a partly statistical distribution o f Zn2+ and N i2+ or C o2+, respectively. Isolated nearly planar B20 5 units connect ribbons consisting o f edge sharing metal octahedra. | | | |
