Crystal structure of an unknown tetra-hydro-furan solvate of tetra-kis-(? 3-cyanato-?(3) N:N:N)tetra-kis-[(triphenyl-phosphane-?P)-silver(I)].

ABSTRACT: In the title compound, [{[(C6H5)3P]Ag}4{NCO}4], a distorted Ag4N4-heterocubane core is set up by four Ag(I) ions being coordinated by the N atoms of the cyanato anions in a ? 3-bridging mode. In addition, a tri-phenyl-phosphine ligand is datively bonded to each of the Ag(I) ions. Intra-molecular Ag?Ag distances as short as 3.133?(9)?Å suggest the presence of argentophilic (d (10)?d (10)) inter-actions. Five moderate-to-weak C-H?O hydrogen-bonding inter-actions are observed in the crystal structure, spanning a three-dimensional network. A region of electron density was treated with the SQUEEZE procedure in PLATON [Spek (2015). Acta Cryst. C71, 9-18] following unsuccessful attempts to model it as being part of disordered tetra-hydro-furan solvent mol-ecules. The given chemical formula and other crystal data do not take into account these solvent mol-ecules.
