A second triclinic polymorph of bis(μ-N-nitroso-N-phenylhydroxylaminato)-κ3 O,O′:O′;κ3 O′:O,O′-bis[(N-nitroso-N-phenylhydroxylaminato-κ2 O,O′)lead(II)]

چکیده
The cupferronate ions in the centrosymmetric dinuclear title compound, [Pb(2)(C(6)H(5)N(2)O(2))(4)], O,O'-chelate to the two Pb(II) atoms; two of the four nitroso O atoms are also involved in bridging. The geometries of the five-coordinate Pb(II) atoms in the two independent mol-ecules are Ψ-octa-hedral; if more remote Pb⋯O inter-actions are also considered, the coordination number is increased to six for one mol-ecule and to seven for the other. Their coordination polyhedra are ill defined in the chain motif, which runs along [100].

The neutral binuclear title complex, [Cd(2)(C(16)H(10)NO(2))(4)(C(10)H(8)N(2))(2)], is centrosymmetric, with the inversion center generating the central (μ-O)(2)Cd(2) bridge. The Cd(II) ion is in a strongly distorted CdN(2)O(5) penta-gonal-bipyramidal geometry, defined by two N atoms from one 2,2'-bipyridine ligand and five O atoms from three 2-phenyl-quinoline-4-carboxyl-ate ligands, one monod...

In the centrosymmetric dinuclear title compound, [Pb(2)(C(7)H(5)O(2))(4)(C(12)H(8)N(2))(2)], two Pb(2+) ions are connected by two tridentate bridging benzoate anions. The Pb(2+) ion is seven-coordinated by five O atoms from three benzoate anions and two N atoms from the 1,10-phenanthroline ligands. The benzoate anions adopt two different coordination modes, one bidentate-chelating and one tride...

The title compound, [Pb(2)(C(7)H(5)O(2))(2)(NO(3))(2)(C(12)H(8)N(2))(2)(H(2)O)(2)], crystallizes as a dinuclear centrosymmetric dimer containing two Pb(II) atoms bridged by two benzoate ligands. Each Pb(II) atom is seven-coordinated by a water mol-ecule, a nitrate anion, a 1,10-phenanthroline (phen) ligand and two benzoate anions. The crystal packing is stabilized by O-H⋯O hydrogen bonds and by...
