Abstract

A new Mn-based complex of {[Mn(L) 2 (mi)]·H 2 O} n ( 1 ) (HL = p -hydroxy phenylacetic acid; mi = 1,1’-(1,4-butanediyl)bis(imidazole)), has been synthesized and structurally characterized. Single-crystal X-ray analyses reveal that compound 1 has a dinuclear Mn(II) unit linking by four carboxylate groups. The bridging N-donor ligand with mi links the Mn(II) centers into a 1D double chain. The detailed analyses of Hirschfeld surface and fingerprint plots provide insight into the nature of non-covalent interactions in the title compound. Furthermore, an attempt was made to explain the magnetic property of compound 1 using atoms in molecule (AIM) theory.

Highlights

Coordination polymers (CPs) have attracted intense attention in recent years because of their intriguing structures and potential applications as functional materials [1,2,3]
Flexible carboxylic acids are good candidates for the construction of new coordination polymers as the carboxyl groups can form C-O-M-O cyclic mode with central metal ions, improving the stability of transition metal complexes [4]. Such types of the carboxylate and carboxyl groups are always actively involved in H-bonding interactions, which results in many interesting structures with higher dimensions [5,6,7,8,9,10]
Mn1 is coordinated by three carboxyl groups from three different L ligands, and two N1 and N4 from two mi ligands
