Abstract

The molecular and crystal structure of the [Sr(urea)(NO₃)₂]_n complex was studied to investigate the various intermolecular interactions.

The crystal structure of poly[di-μ₂-nitrato-μ₂-urea-strontium(II)], [Sr(NO₃)₂(CH₄N₂O)]_n, was determined using single-crystal X-ray diffraction. Crystallizing in the orthorhombic space group Aba2, the asymmetric unit consists of an Sr^II cation, two nitrate anions, and two half urea molecules. The Sr^II cation adopts a distorted decahedral geometry coordinated by ten oxygen atoms, with Sr—O bond lengths ranging from 2.573 (3) to 2.847 (5) Å. The nitrate anions act as bidentate ligands, displaying both terminal and bridging coordination modes. The structure features a robust coordination network supported by hydrogen bonding. These results provide insight into the coordination behaviour of Sr^II with nitrate and urea ligands, contributing to the understanding of supramolecular architectures in metal–organic frameworks (MOFs).

期刊介绍： Acta Crystallographica Section E: Crystallographic Communications is the IUCr''s open-access structural communications journal. It provides a fast, simple and easily accessible publication mechanism for crystal structure determinations of inorganic, metal-organic and organic compounds. The electronic submission, validation, refereeing and publication facilities of the journal ensure rapid and high-quality publication of fully validated structures. The primary article category is Research Communications; these are peer-reviewed articles describing one or more structure determinations with appropriate discussion of the science.
