A new polymorph of catena-poly[[tri­aqua­cadmium(II)]-μ(2)-pyrazine-2,3-dicarboxyl­ato]

The title complex, [Cd(C(6)H(2)N(2)O(4))(H(2)O)(3)](n), is a new monoclinic polymorph. The ortho­rhom­bic form has previously been reported [Ma et al. (2006 ▶). Acta Cryst. E62, m2528–m2529]. The Cd—N and Cd—O bond lengths range from 2.265 (3) to 2.333 (3) Å; a weak Cd—O inter­action is also present...

description The title complex, [Cd(C(6)H(2)N(2)O(4))(H(2)O)(3)](n), is a new monoclinic polymorph. The ortho­rhom­bic form has previously been reported [Ma et al. (2006 ▶). Acta Cryst. E62, m2528–m2529]. The Cd—N and Cd—O bond lengths range from 2.265 (3) to 2.333 (3) Å; a weak Cd—O inter­action is also present, the inter­atomic distance being 2.658 (4) Å. The Cd(II) ions, which have a distorted penta­gonal-bipyramidal geometry, are bridged by pyrazine-2,3-dicarboxyl­ato ligands, forming a zigzag chain structure. The chains are connected by O—H⋯O hydrogen bonds into a three-dimensional framework.
