A 2D coordination polymer with brick-wall network topology based on the [Cu(NCS)2(pn)] monomer

The new complex [Cu(NCS)2(pn)] (1) (pn = 1,3-propanediamine) has been synthesized and characterized by elemental analysis, infrared and electronic spectroscopy. Single crystal X-ray diffraction studies revealed that complex 1 is made up of neutral [Cu(NCS)2(pn)] units which are connected by μ-1,3,3-thiocyanato groups to yield a 2D metal-organic framework with a brick-wall network topology. Intermolecular hydrogen bonds of the type NH⋯SCN and NH⋯NCS are also responsible for the stabilization of the crystal structure.
