Tin complexes containing the nitrate group: crystal structure of polymeric (2-aminobenzothiazolato)nitratotin(II)

Abstract

The structure of the title compound was solved from X-ray diffractometer data by Patterson and Fourier methods and refined by least-squares techniques to R 5.9% for 2 166 independent reflections. Crystals are monoclinic, space group P2₁/c, with unit-cell dimensions: a= 9.993(5), b= 6.915(4), c= 13.593(6)Å. β= 91.9(1)°, Z= 4. Co-ordination around tin can be described as tetrahedral and involves two adjacent NO₃^– anions and two organic molecules. There are two longer Sn-O contacts which complete the co-ordination to six. The nitrate group and the organic ligand both bridge two metal atoms in a rather unusual way, causing the structure to be polymeric.
