چکیده
The title compound, [Zn(C(2)N(3))(2)(C(12)H(9)NO)(2)](n), is a polymeric zinc(II) complex with the metal ion located on an inversion centre. The Zn(II) ion is six-coordinated by two N atoms of two 3-benzoyl-pyridine ligands and four N atoms from four dicyanamide ligands, forming a slightly distorted octa-hedral configuration. In the crystal structure, neighboring Zn atoms are linked together by double dicyanamide bridges to form a polymeric zinc(II) complex.
