The control of water pollution has become one of the most pressing issues in recent years. The increasing demand of textile and fibers lead to the use of dye in order to dyeing these materials. The chemicals used in the textile industry cause environmental and health problems. There are several methods of dye removal from the waste waters which include coagulation, ozonation, ultrafiltration, photodegradation, ion-exchange, chemical precipitation and absorption. Applying these methods in water treatment reveal that absorption on various materials like clay, biomass, activated carbon, zeolites, cellulose and other polymers is relatively cheap, compatible and eco-friendly. Metal-organic frameworks (MOFs) and polynuclear coordination clusters attracted attention of scientist as alternatives of above-mentioned materials. Coordination compounds based on aminoalcohols contains hydroxylic groups which enhance absorption of perilous dyes. Hexanuclear iron clusters have been investigated as potential candidates in process of dye absorption [1]. Herein we report the synthesis and structural characterization of a new homometallic hexanuclear iron pivalate cluster containing aminoalcohol ligands as promising materials for dye removal in water treatment. Compound [Fe6O2(piv)6(Hteed)2(ahpy)2] (1) (where Hpiv = pivalic acid; H4teed = N,N,N‘,N‘-tetrakis(2-hydroxyethyl)ethylenediamine; ahpy = 2-amino-3-hydroxypyridine) was obtained by ultrasonic treatment of trinuclear [Fe3O(piv)6(H2O)3](piv) cluster, H4teed and ahpy in acetonitrile solution. X-ray structural analysis revealed that compound 1 crystallizes in the triclinic P-1 space group with following unit cell parameters: a = 12.600(3), b = 13.760(3), c = 24.530(5) Å, α = 92.83(3), β = 99.11(3), γ = 105.18(3)º. Inorganic core consists of two {Fe3O}7+ fragments, connected via μ2-O2 bridges from hydroxyethyl branches of two triple deprotonated Hteed; six bridging pivalates additionally bind iron atoms in 1 (Fig.). Coordination environments of iron atoms are different, displaying O6 (Fe1 and Fe3) and N2O4 (Fe2) distorted octahedrons. The bond distances Fe–O are in the range 1.820(5) – 2.027(6) Å and Fe–N bond distances fit the interval of 2.202(6) – 2.230(7) Å. The BVS calculation and charge balance prove the Fe(III) oxidation state of all iron atoms in the cluster. Further absorption studies will reveal the efficacy of this compound in dye absorption process.
