Beschreibungen/Notizen

• The synthesis and structure of the title compound, (C24H20P)2[Ge(C2O4)3], are reported. The PPh4+ cations in the structure form infinite zigzag chains in which the P⃛P distances alternate between 6.229 (1) and 7.118 (1) Å, and the P⃛P⃛P angle is 131.4 (1) Å. The shorter P⃛P distance is associated with a sixfold phenyl embrace. However, the longer P⃛P distance is associated with both phenyl–phenyl interactions and interactions between the cations and a twofold symmetric [Ge(C2O4)3]2− anion. In the cation–anion interactions, the P⃛O distance is 4.444 (2) Å, the O⃛P—Cdistal angle is 175.0 (1)° and the shortest H⃛O distances are 2.74 and 3.09 Å.
