New Fluoropalladates(II) M2[PdF4] (M = Na, K) and K2RbPdF5For the first time bright yellow single crystals M2[PdF4] (M = Na, K) have been obtained and their structure determined. K2[PdF4] crystallizes monoclinic, space group C2/m-C2h3 (No. 12) with a = 975.2(3) pm, b = 597.6(1) pm, c = 420.2(1) pm, β = 92.17(2)° and Z = 2. Structure related Na2[PdF4] crystallizes monoclinic too, but in space group P21/c-C2h5 (No. 14) with a = 340.88(7) pm, b = 561.1(1) pm, c = 999.2(2) pm, β = 93.97(2)° and Z = 2. K2RbPdF5, yellow, crystallizes tetragonal with a = 724.9(1) pm, c = 627.9(1) pm, Z = 2 and is isotypic with Rb2CsPdF5 (space group P4/mbm-D4h5, No. 127), an ordered structure variant of the Rb3PdF5-type [1].
Notes:
Erstmals konnten leuchtend gelbe Einkristalle M2[PdF4] (M = Na, K) dargestellt und ihre Struktur bestimmt werden. K2[PdF4] kristallisiert monoklin, R.G. C2/m-C32h (Nr. 12) mit a = 975,2(3) pm, b = 597,6(1) pm, c = 420,2(1) pm, β = 92,17(2)° und Z = 2. Strukturverwandtes Na2[PdF4] kristallisiert ebenfalls monoklin, jedoch in der R.G. P21/c-C2h5 (Nr. 14) mit a = 340,88(7) pm, b = 561,1(1) pm, c = 999,2(2) pm, β = 93,97(2)°und Z = 2. K2RbPdF5, gelb, kristallisiert tetragonal mit a = 724,9(1) pm, c = 627,9(1) pm, Z = 2 und ist isotyp zu Rb2CsPdF5 (R.G. P4/mbm-D4h5, Nr. 127), einer geordneten Strukturvarianten des Rb3PdF5-Typs [1].
