Abstract: A copper-strontium heterometallic coordination polymer was synthesized and characterized by elemental analysis and IR spectra. The crystal structure was determined by single-crystal X-ray diffraction analyses. The title complex is a 2D coordination polymer with the chemical formula {[(CuL)2Sr(H2O)·Sr2(H2O)7]·2H2O·0.5CH3OH}n, where H4L=N-(2-hydroxybenzamido)-N'-(3-carboxylsalicylidene)ethylenediamine. Its structural unit is comprised of two adjacent units, which polymerized with each other to form a new layered heterometallic coordination polymer.

Key words: Copper, Strontium, Heterometallic coordination polymer, Crystal structure
