| Abstract: | The reaction of iPr2Si(PH2)2 ( 1 ) with Ca{N(SiMe3)2}2(THF)2] at 25 °C in molar ratio 1:1 yields the compound Ca3{iPr2Si(PH)2}3(THF)6] ( 2 ). Compound 2 consists of two Ca2P3 trigonal bipyramids with one conjoint calcium corner and SiiPr2 bridged phosphorus atoms. In contrast, the same reaction at 60 °C yield the complex Ca({P(SiiPr2)2PH}2(THF)4] ( 3 ). The isotype strontium compound Sr({P(SiiPr2)2PH}2(THF)4] ( 4 ) was obtained from the reaction of iPr2Si(PH2)2 with Sr{N(SiMe3)2}2(DME)2]. The Compounds 2 – 4 were characterised by single crystal X‐ray diffraction, elemental analysis as well as IR and NMR spectroscopic techniques. |
