Crystal structure of a heterometallic coordination polymer: catena-poly[[[tetraaquacobalt(II)]-μ-pyridine-2,6-dicarboxylato-calcium(II)-μ-pyridine-2,6-dicarboxylato] dihydrate]
In the crystal of the title polymeric complex, {[CoCa(C7H3NO4)2(H2O)4]·2H2O}n (1), the CoII ion is N,O,O′-chelated by two pyridine-2,6-dicarboxylate anions in a distorted N2O4 octahedral geometry, and two carboxylate O atoms of pyridine-2,6-dicarboxylate anions bridge tetraaquacalcium(II) units to f...

| Summary: | In the crystal of the title polymeric complex, {[CoCa(C7H3NO4)2(H2O)4]·2H2O}n (1), the CoII ion is N,O,O′-chelated by two pyridine-2,6-dicarboxylate anions in a distorted N2O4 octahedral geometry, and two carboxylate O atoms of pyridine-2,6-dicarboxylate anions bridge tetraaquacalcium(II) units to form polymeric chains propagating along the b-axis direction. In the crystal, O—H...O and C—H...O hydrogen bonds, and offset π–π stacking interactions [intercentroid distances = 3.551 (1) and 3.746 (1) Å] involving inversion-related pyridine rings link the polymeric chains and lattice water molecules to form a supramolecular three-dimensional framework. |
