摘要

Mg15Ir5Si2 (tetragonal, P4(2), a 1371.7(1) pm, c = 873.0(2) pm, Z=4, 1497 reflections, 103 parameters, R1 = 0.048) was prepared by reaction of the elements at 900 degreesC in sealed tantalum ampoules. The compound is the silicide with the highest alkaline earth metal content known so far. It is the first example of a silicide with an isolated transition metal silicon building group embedded in a matrix of non-transition metal atoms. The structure contains planar Ir2SiIrSiIr2 groups with silicon atoms in nearly trigonal planar coordination of three iridium atoms (d(Ir-Si) 235 and 236 pm). [References: 14]
