Das Cäsiumsalz eines polydentaten Sauerstoffliganden. Synthese und zweidimensionale Schichtstruktur von Cs[(C5H5)Co{PO(OCH3)2}3]

The Cs salt CsL OMe ≡ Cs[(C 5 H 5 )Co{PO(OCH 3 ) 2 } 3 ] was obtained from the chloride of the diprotonated ligand L OMe and CsOH . H 2 O. Crystals were grown from a mixture of 1,2-dichloroethane/diethylether. They belong to the monoclinic space group P2 1 /c with lattice parameters a = 12.390(4) A, b = 12.223(8) A, c = 13.248(8) A, β = 100.58(4)°. The structure was solved by Patterson and Difference Fourier methods. Refinement converged at R = 0.063, R w = 0.071 for 2110 reflections and 227 parameters
