Truncation of Unitary Operads

We introduce truncation ideals of a $\Bbbk$-linear unitary symmetric operad and use them to study ideal structure, growth property and to classify operads of low Gelfand-Kirillov dimension

{6,6′-Dimethoxy-2,2′-[cyclo­hexane-1,2-diylbis(nitrilo­methyl­idyne)]diphenolato-κ4 O 1,N,N′,O 1′}iron(II) monohydrate

In the title complex, [Fe(C22H24N2O4)]·H2O, the FeII center is four-coordinated by two O and two N atoms from 2,2′-[6,6′-dimethoxy­cyclo­hexane-1,2-diylbis(nitrilo­methyl­idyne)]diphen­olate (L) ligands in a distorted square-planar geometry. Uncoordinated water and FeL mol­ecules are paired via inter­molecular water–meth­oxy O—H⋯O hydrogen bonds
