(4′-Phenyl-2,2′:6′,2′′-terpyridine-κ3N,N′,N′′)bis-(thio-cyanato-κN)zinc(II) unknown solvate

摘要

The title compound, [Zn(NCS)2(C21H15N3)], crystallizes with three independent complex molecules in the asymmetric unit. In each complex molecule, the ZnII atom is coordinated by three N atoms of a 40 -phenyl-2,20 :60 ,200-terpyridine ligand, and by the N atoms of two NCS anions. The ZnII atoms are therefore fivecoordinate, ZnN5, with distorted square-pyramidal geometries. In the crystal, the three independent molecules are linked by a series of offset – interactions [intercentroid distances vary between 3.680 (5) and 3.791 (5) A? ], forming columns along the a-axis direction. The columns are linked via C—HS interactions, forming a fence-like arrangement parallel to the ab plane. A small region of disordered electron density was corrected for using the SQUEEZE routine in PLATON [Spek (2015). Acta Cryst. C71, 9–18], but the formula mass and unit-cell characteristics were not taken into account during the refinement.
