Poly[(μ3-nicotinato-κ3 O:O′:N)(μ2-nicotinato-κ3 O,O′:N)iron(II)]
In the crystal structure of the title compound, [Fe(C(6)H(4)NO(2))(2)](n), one nicotinate group O,O'-chelates one Fe atom and binds through the N atom to the other Fe atom; the second nicotinate group bridges three Fe atoms through the N and two O atoms. The μ(2)- and μ(3)-bridging modes of the two nicotinate groups result in a polymeric three-dimensional network structure. The Fe atom shows oc...

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. Ad...

The dinuclear mol-ecule of the title compound, [Cd(2)(C(6)H(4)NO(2))(4)(C(2)H(8)N(2))(2)(H(2)O)(2)]·2H(2)O, lies on an inversion centre and forms 12-membered (CdNC(3)O)(2) metallacycles with the two Cd(2+) ions bridged by two nicotinate ligands. Both Cd(2+) ions display coordination polyhedra with a distorted octa-hedral geometry that includes two pyridine N atoms from bridging and terminal nic...

In the title mol-ecule, [Sn(C(7)H(6)Cl)(2)(C(6)H(4)NO(2))(2)(H(2)O)], the O atoms of the two chelating nicotinate groups and the O atom of the coordinated water mol-ecule comprise the penta-gonal plane of the trans-C(2)SnO(5) penta-gonal-bipyramid [C-Sn-C = 178.62 (11) °] surrounding the Sn(IV) atom. In the crystal, adjacent mol-ecules are linked by O-H⋯N hydrogen bonds, generating a chain runn...

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...
