On Complex Fluorides of Divalent PalladiumFor the first time single crystals of the new compounds RbPdPdF5, KPdPdF5, and K2CsPdF5 have been obtained. Orange brown RbPdPdF5 crystallizes orthorhombic, space group Imma-D2h28 (No. 74) with a = 633.6(1) pm, b = 765.5.(1) pm, c = 1067.5(1) pm and Z = 4 and is isotypic with CsPdPdF5 [1]. Structure related KPdPdF5 (also orange brown) crystallizes orthorhombic too, but in space group Pnma-D2h16 (No. 62) with a 614.12(9) pm, b = 748.7(1) pm, c = 1065.0(2) pm and Z = 4. K2CsPdF5, light yellow, crystallizes tetragonal with a = 736.3(1) pm, c = 628.0(1) pm, Z = 2, and is isotypic with Rb2CsPdF5 (space group P4/mbm—D4h5 Nr. 127), an ordered structure variant of the Rb3PdF5-Type [1].
Notes:
Neu dargestellt wurden RbPdPdF5, KPdPdF5 und K2CsPdF5, alle in Form von Einkristallen. Orangebraunes RbPdPdF5 kristallisiert orthorhombisch, R. G. Imma-D2h28 (Nr. 74) mit a = 633,6(1) pm, b = 765,5(1) pm, c = 1067,5(1) pm und Z = 4 und ist isotyp zu CsPdPdF5 [1]. Strukturverwandtes KPdPdF5 (ebenfalls orange-braun) kristallisiert gleichfalls orthorhombisch, jedoch in der R. G. Pma—D2h16 (Nr. 62) mit a = 614,12(9) pm, b = 748,7(1) pm, c = 1065,0(2) pm und Z = 4. K2CsPdF5, hellgelb, kristallisiert tetragonal mit a = 736,3(1) pm, c = 628,0(1) pm Z = 2, ist isotyp zu Rb2CsPdF5 (R. G. P4/mbm—D4h5) (Nr. 127) und somit ein weiterer Vertreter der geordneten Strukturvariante des Rb3PdF5-Typs [1].
