    Description / Table of Contents: Complex Stabilized Tris(hydroxy)phosphane, P(OH)3Hydrolysis of (CO)5Cr · PCl3 in the presence of triethylamine yields Et3NH[(CO)5Cr · P(OH)2O] which can be converted into the free acid by cation exchange. The acid was isolated as the monohydrate (CO)5Cr · P(OH)3 · H2O. This shows that phosphorous acid is stabilized as the tris(hydroxy)phosphan tautomer by complex formation.(CO)5Cr · P(OH)3 is a weaker acid than OP(OH)3 and it reduces Ag+ to the metal.
    Notes: Die Hydrolyse von (CO)5Cr · PCl3 in Gegenwart von Triethylamin liefert Et3NH[(CO)5Cr · P(OH)2O], das durch Kationenaustausch in die freie Säure überführt und als kristallines Hydrat (CO)5Cr · P(OH)3 · H2O isoliert werden kann. Somit ist phosphorige Säure am Komplex als Tris(hydroxy)phosphan-Tautomeres stabilisierbar.(CO)5Cr · P(OH)3 ist eine schwächere Säure als OP(OH)3; sie reduziert Ag+ zum Metall.
