Poly[(acetato-κ2O,O′)aqua(μ4-1H-benzimidazole-5,6-dicarboxylato-κ6N3:O5,O5′:O5,O6:O6′)cerium(III)]
In the title compound, [Ce(C9H4N2O4)(C2H3O2)(H2O)]n, the CeIII ion is coordinated by five O atoms and one N atom from four 1H-benzimidazole-5,6-dicarboxylato (L) ligands and by two O atoms from an acetate ligand and one aqua ligand, forming a slightly distorted tricapped trigonal–prismatic geometry. The L ligands are bridging, forming a layered polymer parallel to (010). In the crystal, O—HO and N—HO hydrogen bonds connect the polymer layers into a three-dimensional network.

The title compound, [Mn(C6H4N5O)2(H2O)4], is isotypic with its Zn, Ni and Cd analogues reported recently. In the crystal, the MnII cations are coordinated by four O atoms from four aqua ligands and two N atoms from two 5-(pyridin-4-yl)tetrazolide N5-oxide ligands in a distorted octahedral coordination environment. The asymmetric unit consists of one MnII cation located on a crystallographic twofold axis, and two crystallographically independent water molecules and one N-donor ligand in general positions. The discrete complex molecules are arranged in alternating rows parallel to [100] and are linked by O—HN and O—HO hydrogen bonds into a three-dimensional network.
