摘要：
The new compounds BaRh2Si2 (monoclinic, P2(1)/c, a = 792.6(1) pm, b = 664.5(7) pm, c = 767.9(4) pm, beta = 91.2(1)degrees, Z = 4, 2867 reflexions, 47 parameters, R = 0.024), BaIr2Si2 (monoclinic, P2(1)/c, a = 792.47(6) pm, b = 664.28(6) pm, c = 772.22(6) pm, beta = 92.181(7)degrees, Z = 4, 1939 reflexions, 47 parameters, R = 0.037) and BaPt2Ga2 (monoclinic, P2(1)/c, a = 850.4(1) pm, b = 647.3(1) pm, c = 819.8(1) pm, beta = 95.97(1)degrees, Z = 4, 1506 reflexions, 47 parameters, R = 0.038) were prepared by reaction of the elements. Their structures were determined from single crystal data. The compounds crystallize isotypically with a distortion variant of the CaRh2B2 type of structure.
