Low-temperature redetermination of aqua-chloridotriphenyl-tin(IV)-1,10-phenanthroline (1/1).

The crystal structure of the title compound, [Sn(C(6)H(5))(3)Cl(H(2)O)]·C(12)H(8)N(2), which was refined in the triclinic space group P [Fu, Gao, Ma & Zhang (2005 ▶). Chin. J. Synth. Chem. 13, 55-57], has been redetermined in the monoclinic space group C2/c from low-temperature diffraction measurements. The Sn atom is five-coordinate in a trans-C(3)SnClO trigonal-bipyramidal geometry; the coordinated water mol-ecule forms a pair of hydrogen bonds to the nitro-gen heterocycle.
