Abstract
The title compound, [Ag(CN)(PTA)
]·4H
O, is a water-soluble discrete silver(I) complex where the silver center is coordinated by three phospho-rus atoms from distinct 1,3,5-tri-aza-7-phosphaadamantane (PTA, C
H
N
P) ligands and one carbon atom from a cyanide ion, forming a distorted tetra-hedral geometry. The asymmetric unit consisting of a [AgCN(PTA)
)] unit and two water mol-ecules. The Ag-P bond distances range from 2.4696 (4) to 2.4728 (6) Å, and the Ag-C bond distance is 2.168 (2) Å, while the bond angles around the silver center vary between 107.402 (13) and 111.07 (3)°, confirming its distorted tetra-hedral coordination environment. Inter-molecular O-H⋯N and O-H⋯O hydrogen bonds in the crystal packing of the title compound generate a two-dimensional supra-molecular architecture with a corrugated sheet-like topology that extends along the crystallographic
plane.
