Sažetak
The title compound, [Hg(SCN)2(C6H5)P(C12H8)]2, exists as a dimer with two-fold crystallographic symmetry in the solid state with the Hg atoms linked by bridging N- and S-thiocyanato atoms. There are four primary bonds to each Hg atom, Hg−N, 2.771(4) A, Hg−P, 2.4084(11) Å and two Hg−S, 2.4565(10) Å and 2.6055(13) Å, result-ing in a distorted trigonal pyramidal geometry about the metal centre. The dimers associate about inversion centres to form infinite one-dimensional chains by weaker Hg⋅⋅⋅N 3.178(5) Å and Hg⋅⋅⋅S 3.6027(14) Å interactions, giving an overall distorted octahedral coordination geometry for each Hg atom. The Hg⋅⋅⋅P bond lies approximately orthogonal to the ⋅⋅Hg⋅⋅Hg⋅⋅ chain and the benzophosphole group forms a 'sandwich5 preventing interactions between the Hg(SCN)2 moieties in neighbouring chains.
