(2,2′‐Bi­pyridine‐κ2N)­bis­[N‐(2‐pyridyl‐κN)‐p‐toluene­sulfon­amido‐κN]zinc(II)

The structure of the title compound, Zn(C₁₂­H₁₁­N₂­O₂S)₂(C₁₀H₈N₂)], consists of monomeric mol­ecules in which the central ZnN₂N′N′′ unit has a distorted tetrahedral geometry, with bond lengths ranging from 2.020 (3) to 2.109 (3) Å. The anionic ligands are potential bidentate donors and thus there are two secondary Zn—N interactions. The shorter of these is 2.317 (3) Å and completes at the Zn atom an irregular five‐coordinated geometry, which can be described as a square pyramid showing 30% distortion towards the trigonal bipyramid; the other Zn—N contact is much longer at 2.549 (3) Å.
