Abstract
The new compounds Ca3Pd2Ga2, Ca3Pt2Ga2, Ca3Rh2Ga3, and Ca3Ir2Ga3 were prepared by heating appropriate mixtures of the elements under an Argo n-atmosphere. The results of the structure analysis of single crystals by means of X-ray diffraction are given in the section ''Inhaltsubers icht''. Ca3Pd2Ga2 and Ca(3)Pt(2)Ga2 are isotypic and form the Y3Rh2Si2 type structure (Pbcm), where the platinium metals have a trigonal env ironment consisting of Ga-atoms. The isotypic compounds Ca3Rh2Ga3 and Ca3Ir2Ga3 (Pbcm) form a new type of structure, which is related to the Y3Rh2Si2 type with a distorted tetrahedral surrounding of Ga-atoms fo r Rh (resp. Ir).
