Über Komplexstabilisiertes Tris(hydroxy)phosphan, P(OH)3

Abstract: 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.

“…The isolation and X-ray crystal structures of complexes of P(OH) 3 and As(OH) 3 are reported for the first time in this work. Coordination is to the Pd site of a heterometal cuboidal cluster cation with the Mo 3 PdS 4 4+ core . The addition of PCl 3 or NaAsO 2 to solutions of [Mo 3 (PdCl)S 4 (H 2 O) 9 ] 3+ (the chloride is attached to the Pd, and the nine H 2 Os to the 3 × Mo sites, which have less affinity for Cl - ) in HCl is accompanied by rapid color changes from blue to brown as a result of following reactions: The formation of [Mo 3 PdP(OH) 3 S 4 Cl n (H 2 O) 9 - n ] (4- n )+ complexes in solution was appropriately monitored by 31 P NMR spectroscopy.…”
