Crystal structure and Hirshfeld surface analysis of poly[[tetraaqua(μ-1,3,4,7,8,10,12,13,16,17,19,22-dodecaazatetracyclo[8.8.4.13,17.18,12]tetracosane-5,6,14,15,20,21-hexaonato)iron(IV)dilithium] tetrahydrate]

The title compound, [FeLi 2 (C 12 H 12 N 12 O 6 )(H 2 O) 4 ]·4H 2 O, consists of iron complex anions, lithium cations and water molecules. The complex anion shows a clathrochelate topology. The coordination geometry of the Fe IV centre is intermediate between a trigonal prism and a trigonal antiprism. In the crystal, the complex anions are connected through two Li cations into dimers, which are connected by Li—O bonds, forming infinite chains along the b- axis direction.
