Preparation, crystal and molecular structure, and antimony-121 Mössbauer spectrum of trifluoro(1,10-phenanthroline)(thiourea)antimony(III)

Abstract

The mixed (1 : 1 : 1) adduct between SbF3,1,10-phenanthroline, and thiourea has been prepared. The compound has been characterized via Mössbauer spectroscopy and X-ray analysis on a single crystal. It crystallizes in the triclinic space group P[1 with combining macron] with a= 7.736(1), b= 10.443(1), c= 10.509(1)Å, α= 92.3(1), β= 108.9(1), γ= 111.1(1)°, and Z= 2. The structure was solved by Patterson and Fourier methods; full-matrix least-squares refinement based on 3 340 observed reflections gave a final R= 0.026 (R′= 0.030). The distorted octahedral co-ordination polyhedron is characterized by very asymmetrical bonds to the central ion [Sb–F(1) 1.938(2), Sb–F(2) 1.997(2), Sb–F(3) 1.948(2), Sb–N(1) 2.556(3), Sb–N(2) 2.731(3)Å] and by a relatively short Sb ⋯ S interaction of 3.061 (3)Å. The whole structure is held together by intermolecular hydrogen bonds.
