A recurrent motive in the supramolecular assembly of coordination compounds with 2,6-bis(benzimidazol-2-yl) piridine (Bzimpy) and two identical H-bond acceptor co-ligands: [Cd(Ac)2(Bzimpy)], [Zn(Ac)2(Bzimpy)]?H2O (Ac: acetato) and related compounds

Resumen

We report the crystal structures of two novel coordination compounds with similar complex composi- tion: [Cd(Ac)2(Bzimpy)] (I) and [Zn(Ac)2(Bzimpy)]-H2O (II). Both compounds are monomeric. Compound I con- sists of a Cd(II) center heptacoordinated with three N atoms from a Bzimpy molecule and four O atoms from two bidentate acetato molecules. Compound II consists of a Zn(II) center pentacoordinated with three N atoms from a Bzimpy molecule and two O atoms from two monodentate acetato molecules. A non-coordinated water molecule completes the formula. In addition, we highlight some common features in the supramolecular assembly of both compounds and with similar structures deposited in the version 5.33 of the CSD. This assembly occur through H-bridges and p–p offset stacked interactions, giving rise to the formation of what we call ‘‘directed ring’’ of two types: two molecular components 2Rd and three molecular components 3Rd. Structures are viewed as composed of well defined substructures in order to analyze them.
