✦ Synopsis

Reaction of 2,4-dihydroxybenzaldehye salicylhydrazide (L) with Zn(OAc) 2 Á2H 2 O in a mixed solvent of pyridine and N,Ndimethylformamide (DMF) resulted in the formation of the title complex, [Zn 2 (C 14 H 10 N 2 O 4 ) 2 (C 5 H 5 N) 2 ]Á2C 3 H 7 NO. The asymmetric unit contains one complete neutral zinc complex and one-half of a second complex with crystallographic inversion symmetry, together with three DMF solvent molecules. The Zn atoms, all having the same coordination geometry, are coordinated by three O atoms and two N atoms in a distorted tetragonal-pyramidal geometry, with phenolate O atoms acting as bridges between the Zn atoms.

Symmetry code: (i) Àx; Ày þ 2; Àz þ 2.

In the title compound, [Zn 2 (C 14 H 8 N 2 O 4 )(C 2 H 8 N 2 ) 2 ]Á2C 3 H 7- NOÁ2H 2 O, the Zn 2 complex molecule lies on a crystallographic inversion centre. The two Zn atoms are bridged by two diazine N atoms of a 1,2-bis(salicyloyl)hydrazine(4À) ligand (bsh 4À ); the inversion centre is located a
