Crystal structure and Hirshfeld surface analysis of poly[[tetraaqua(-1,3,4,7,8,10,12,13,16,17,19,22-dodecaazatetracyclo[8.8 .4.1^3,17.1^8,12]tetracosane-5,6,14,15,20,21-hexaona to)iron(IV)dilithium] tetrahydrate]

The title compound, [FeLi2(C12H12N12O6)(H2O)(4)]center dot 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.
