ABSTRACT
The title compound, Ag ( PPh3) 3 ( CN )·(DMF) · 0.5(H20),crystallizes in triclinic, space group *.The largest peak and hole on the final difference Fourier map were 1.192 and * , respectively . The compound comprises a separated Ag(CN)(PPh3)3 moiety, one isolated N,N'-dimethylformamide(DMF) solvent molecule, and half water molecule in the crystallographic asymmetric unit. The silver cation in the Ag(CN)(PPh3)3 moiety locates in a distorted tetrahedral coordination environment, and its coordinated by three triphenylphosphor(Ph3P) ligands and one cyanide group. The Ag(CN)(PPh3)3 moieties stack together via weak * and intermolecular interations to form a 3-d structure with a 1-d channel along the c direction, in which the DMF and water molecules locate.
