Dibromidobis(1,10-phenanthroline-?N,N')cadmium(II).

ABSTRACT: The title compound, [CdBr(2)(C(12)H(8)N(2))(2)], synthesized by the hydro-thermal reaction of Cd(CH(3)COO)(2)·2H(2)O with NaBr and 1,10-phenanthroline, has the Cd(II) cation coordinated by two Br(-) anions and four N atoms from two 1,10-phenanthroline ligands in a distorted octa-hedral geometry. The crystal packing is stabilized by inter-molecular ?-? inter-actions with centroid-centroid distances 3.572?(1) and 3.671?(1)?Å together with C-H?Br hydrogen bonds.

Project description:In the title mononuclear complex, [Cd(C(12)H(8)N(2))(H(2)O)(4)]SO(4)·2H(2)O, the coordination geometry around the Cd(II) atom is a distorted octa-hedron, with two aqua ligands occupying the axial positions.

catena-Poly[[(1,10-phenanthroline-?N,N')cadmium(II)]-?-oxalato-?O,O:O,O].

Project description:In the title complex, [Cd(C(2)O(4))(C(12)H(8)N(2))](n), the Cd(II) atom has a distorted octa-hedral coordination, defined by four O atoms from two symmetry-related oxalate ligands and by two N atoms from a bidentate 1,10-phenanthroline ligand. Each oxalate ligand bridges two Cd(II) atoms, generating a zigzag chain structure propagating along [100]. The packing of the structure is consolidated by non-classical C-H?O hydrogen-bonding inter-actions.

catena-Poly[[aqua-(1,10-phenanthroline)cadmium(II)]-μ-benzene-1,4-di-carboxyl-ato].

Project description:The title compound, [Cd(C(8)H(4)O(4))(C(12)H(8)N(2))(H(2)O)](n), is a new coordination polymer of benzene-1,4-dicarboxyl-ate with cadmium(II) and 1,10-phenanthroline. The Cd(II) ion is coordinated by two N atoms from the 1,10-phenanthroline mol-ecule, three O atoms from two crystallographically independent benzene-1,4-dicarboxyl-ate ligands and the O atom of a coordinated water mol-ecule, forming a heavily distorted octa-hedron. The 1,10-phenanthroline ligand is approximately planar within 0.073 (4) Å. The two different benzene-1,4-dicarboxyl-ate ligands each coordinate to two Cd(II) ions in bidentate and monodentate modes, forming an infinite zigzag chain. Adjacent chains are packed tightly by strong π-π inter-actions [centroid-centroid distances = 3.851 (2) and 3.859 (2) Å] between the aromatic rings of the benzene-1,4-dicarboxyl-ate ligand and the 1,10-phenanthroline of a neighboring chain, forming a sheet parallel to (011). Different sheets are linked together via O-H⋯O hydrogen bonds between the coordinated water mol-ecules and the O atoms of the carboxyl-ate groups, forming a three-dimensional network.

catena-Poly[di-?(1,1)-azido-(1,10-phenanthroline)cadmium(II)].

Project description:The asymmetric unit of the title Cd(II) compound, [Cd(N(3))(2)(C(12)H(8)N(2))](n), contains a Cd(II) atom, located on a twofold axis passing through the middle of the phenanthroline mol-ecule, one azide ion and half of a 1,10-phenanthroline mol-ecule. The Cd(II) atom exhibits a distorted octa-hedral coordin-ation including one chelating 1,10-phenanthroline ligand and four azide ligands. The crystal structure features chains along the c direction in which azide groups doubly bridge two adjacent Cd(II) atoms in an end-on (EO) mode. Inter-chain ?-? stacking inter-actions, with centroid-centroid separations of 3.408?(2)?Å between the central aromatic rings of 1,10-phenanthroline mol-ecules, lead to a supra-molecular sheet parallel to the bc plane.

Dibromido(2,9-dimethyl-1,10-phenanthroline-?N,N')cadmium.

Project description:In the title complex, [CdBr(2)(C(14)H(12)N(2))], the Cd(II) ion is tetra-coordinated by two N atoms of the bidentate 2,9-dimethyl-1,10-phenanthroline ligand and two bromide ions in a substanti-ally distorted CdN(2)Br(2) tetra-hedral geometry.

Aromatic ?-? stacking [shortest centroid-centroid separation = 3.633?(2)?Å] inter-actions occur within, and also link, the dimers into chains propagating parallel to [100].
