Synthesis,Crystal and Molecular Structure of 2‐Pyridylethanolbis(saccharinato)mercury(II)

2‐Pyridylethanolbis(saccharinato)mercury(II), [Hg(sac)2(pyet)], where sac and pyet are the saccharinate anion and the 2‐pyridylethanol molecule, respectively, crystallizes in the triclinic space group P (No. 2) with a = 10.4518(6), b = 11.3796(6) (5), c = 19.9945(12) Å, a = 102.758(3)° b = 98.146(3)°, g = 104.751(3)°, Z = 4, V = 2193.0(2) ų. The unit cell contains two crystallographically independent [Hg(sac)2(pyet)] units in which the mercury(II) ion is tetrahedrally coordinated by two nitrogen atoms of two sac ligands, and one nitrogen and one oxygen atoms of one neutral pyet ligands. The pyet acts as a bidentate N‐ and O‐donor ligand forming a six‐membered chelate ring, while sac behaves as a monodentate N‐donor ligand. The average bite angle of the pyet ligand is 75.8(5)°. The Hg‐N_sac bond distances are in the range 2.0874(18) and 2.1931(18) Å, whereas the Hg‐N_pyet and Hg‐O_pyet bond distances are 2.2452(19)‐2.3202(19) and 2.6036(17)‐2.5902(16) Å, respectively. The crystal exhibits two strong hydrogen bonds between the hydroxyl O atom of pyet and sulfonyl O atoms of sac and the C‐H…O type weak hydrogen bonds between H atoms of the aromatic rings of the pyet and the sulfonyl O atoms of the sac ligands. Furthermore, packing of the molecules in the solid‐state results in aromatic π‐π interactions associated with the aromatic rings of sac‐sac and py‐py.
