摘要
The first known example of a regular face-sharing icosahedra helix is presented in the novel crystal Structure Of delta-Co2Zn15, solved and refined from single-crystal X-ray and neutron powder diffraction data. The compound delta-Co2Zn15 is also the first example of an intermetallic compound crystallizing in the acentric hexagonal space group P6(2). The parameters from the single crystal refinement are a = 11.292(2) Angstrom, c = 7.750(l) Angstrom, Z = 4, and R-w = 0.025. (C) 2002 Elsevier Science (USA).
