Poly[(μ6-benzene-1,3,5-tricarboxylato- κ6O1:O1′:O3:O 3′:O5:O5′)tris(N,N- dimethylformamide-κO)tris(μ3-formato-κ3 O:O:O′)trizinc(II)]

초록

The asymmetric unit of the title compound, [Zn3(HCO2) 3(C9H3O6)(C3H 7NO)3]n, contains one Zn ion, one formate ligand, one N,N-dimethylformamide (DMF) ligand and one-third of a benzene-1,3,5-tricarboxylate (btc) ligand situated on a crystallographic 3 axis. Each ZnII atom is coordinated by one O atom from a DMF ligand, two O atoms from two btc ligands and three O atoms from three formate ligands in a distorted octahedral geometry. The ZnII atoms are connected by the formate and btc ligands, forming hexanuclear cores, which are linked by btc ligands, constructing a two-dimensional layered network along the ab plane.
