| Summary: | Two nicotinate binding modes are observed in the dinuclear title compound, [Sn-2(C7H6Br)(4)(C6H4NO2)(4)(H2O)(2)]: in the first, a terminal O,O'-chelating molecule binds to a water-coordinated diorganotin cation, while the second mode corresponds to an O:N-bridging molecule which binds to two cations. The two Sn atoms exist in trans-C2SnNO4 pentagonal-bipyramidal geometries. Adjacent dinuclear units are linked by O-H...N hydrogen bonds, generating a linear chain, which propagates in the b-axis direction. O-H...O interactions are also observed. |
