چکیده
Two nicotinate binding modes are observed in the dinuclear title compound, [Sn(2)(C(7)H(6)Br)(4)(C(6)H(4)NO(2))(4)(H(2)O)(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-C(2)SnNO(4) penta-gonal-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 inter-actions are also observed.

In the title compound, {[Ag(2)Pr(C(6)H(4)NO(2))(4)(H(2)O)(4)]ClO(4)·H(2)O}(n), the Pr(III) atom, lying on a twofold rotation axis, has a distorted square-anti-prismatic coordination geometry, defined by four O atoms from four nicotinate (nic) ligands and four water mol-ecules. The Ag(I) atom is coordinated in an almost linear fashion by two pyridyl N atoms from two nicotinate ligands. The linea...
