A novel lamellar coordination polymer incorporating partially overlapped helices, ladders and zigzag chains – Synthesis, crystal structure and magnetic property

The hydrothermal assembly of CoCl2 · H2O with benzene-1, 2, 3, 4-tetracarboxylic acid (H4mpda) yielded a novel lamellar coordination polymeric complex, Co2mpda(H2O)6 · H2O (1), in which each layer presents an interesting multifold topology: both as partially overlapped helices with alternate chirality and as alternately arranged ladders and zigzag chains.
