Synthesis and crystal structure of one-dimensional copper(II) coordination polymer bridged by pyrazine derivative
The one-dimensional copper(II) coordination polymers [Cu(tdpd)(pda)](n) (1) (H(2)tdpd = 1,4,5,6-tetrahydro-5,6-dioxo-2,3-pyrazinedicarbonitrile, pda = 1,2-phenylenediamine) has been synthesized and characterized. Compound I is a linear chain of copper(II) ions bridged by tdpd(2-) dianion with terminal pda ligand. Magnetic susceptibility measurement shows antiferromagnetic couplings between the copper(II) ions.
