Abstract top

The centrosymmetric trinuclear title compound, [Zn3(C2H3O2)2(C7H5O3)4(C12H8N2)2], has six carboxylate groups each bridging two metal centers. The Zn atom on a center of inversion is coordinated by six O atoms in an octahedral environment. The other Zn atoms are each chelated by the N-heterocycle, and their coordination number is also six as the acetate group also functions as a chelating group. The hydroxy group of one of the two symmetry-independent salicylate groups is disordered over two positions in a 2:1 ratio.

Comment top

The 2,2'-bipyridine adduct of zinc disalicylate exists in two form, a monomeric form (Lemoine et al., 2004) and a cyclotetrameric form (Wang et al., 2004). The attempt to synthesize the 1,10-phenanthroline analog gave the trinuclear compound in which part of the acetate entity that was present as the counterion is incorporated. The centrosymmetric trinuclear compound has six carboxylate groups each bridging two metal centers. The zinc atom on a center-of-inversion is coordinated to six oxygen atoms in an octahedral environment. The other zinc atoms are each chelated by the N-heterocycle, but their coordination number is six as the acetate group that is engaged in bridging also functions as a chelating group (Fig. 1).

Related literature top

For the structure of the diaquazinc derivative of salicylic acid, see Klug et al. (1958). The monomeric 2,2'-bipyridine adduct is reported by Lemoine et al. (2004) and the cyclic tetramer by Wang et al. (2004)

Experimental top

A solution of salicylic acid (1.0 mmol, 0.138 g) and sodium hydroxde (1.0 mmol, 0.040 g) in methanol (8 ml) was added to a solution of zinc acetate (1.0 mmol, 0.183 g) in methanol (8 ml). 1,10-Phenanthroline (1.0 mmol, 0.180 g), dissolved in methanol (5 ml), was then added. The mixture was placed in a 25-ml Teflon-lined stainless-steel Parr bomb. The bomb was heated at 363 K for five days. Colorless prismatic crystals were collected manually from the cool solution.

Refinement top

The hydroxy group of one of the two salicylate groups is disordered over two positions. The phenylene ring was refined as a rigid hexagon of 1.39 Å sides, and the hydroxy group was placed on both ortho-positions, subject to the two C–O distances being within 0.01 Å of each other. These were restrained to be nearly coplanar with the ring.

Carbon-hydrogen atoms were placed in calculated positions (C—H 0.93 Å), and were included in the refinement in the riding model approximation, with their temperature factors set to 1.2 times the Ueq of the parent atoms.
