 Title    Die Kristallstruktur von 2.2'-Bipyridin-bis(brenzkatechyl)phosphoniiim- hexafluorophosphat Crystal Structure of 2,2'-Bipyridine-bis(o-phenylenedioxy)phosphonium Hexafluorophosphate  
 Abstract    2,2'-Bipyridine-bis(o-phenylenedioxy)phosphonium hexafluorophosphate crystallises in the monoclinic space group C2/c (Z = 8) with a = 18.654(4), b = 10.131(2), c = 24.344(4) A, ß = 99.53(4)°. The cationic phosphorus atom displays an octahedral coordination slightly distorted towards the tetrahedral one of an uncomplexed phosphonium center. The OPO bond angles are between 91.6 and 95.7(2)°, the NPN angle of the bipyridine chelate ring in contrast is only 81.7(2)°. The ring systems of the bipyridine ligand are inclined slightly to one another at an angle of 4.7°. The bond lengths to the cationic phosphorus are P-0 1.668-1.672(3), P-N 1.896(4) and 1.898(4) A. The hexafluorophosphate anion is disordered.
