Catena-Poly[[(1,10-phenanthroline-?² N,N')lanthanum(III)]-?-(5-bromo-2-hy-droxy-benzoato)-?² O¹:O¹'-di-?-chlorido].

ABSTRACT: In the title complex, [La(C?H?BrO?)Cl?(C??H?N?)](n), the La(III) ion is eight-coordinated by two carboxyl-ate O atoms from two 5-bromo-salicylate ligands, two N atoms from a chelating 1,10-phenanthroline ligand and four bridging Cl atoms in a distorted square-anti-prismatic geometry. The La(III) ions are linked by bridging carboxyl-ate groups and chloride anions into a chain along [100]. An intra-molecular O-H?O hydrogen bond is formed in the 5-bromo-salicylate ligand. ?-? inter-actions between the pyridine and benzene rings and between the benzene rings are observed [centroid-centroid distances = 3.794?(5) and 3.804?(4)?Å].

The crystal structure is stabilized by ?-? inter-actions between the 1,10-phenanthroline and 5-chloro-salicylate ligands, the shortest centroid-centroid separation between neighbouring aromatic rings being 3.652?(1)?Å.

Inter-molecular ?-? stacking is observed between adjacent complexes [inter-planar distance = 3.461?(3)?Å]. Intra- and inter-molecular O-H?O hydrogen bonds are observed in the DHB ligands and between a water mol-ecule and DHB ligands, respectively. O-H?N hydrogen bonds are also observed in the DHB ligands and between uncoordinated phen mol-ecules and aqua ligands.

Project description:In the title compound, [Pb?(C?H?O?S)?(C??H?N?)?(H?O)?]·CH?COOH, the seven-coordinate Pb(II) atom is chelated by two N atoms of one 1,10-phenanthroline ligand, four O atoms from three 5-sulfosalicylate dianions and one water O atom. Each dianion serves as a bridging ligand, connecting adjacent Pb(II) atoms into a centrosymmetric polymeric chain extending parallel to [001]. There are ?-? inter-actions between the aromatic systems of neighbouring dianions, with plane-to-plane distances of 3.371?(2)?Å, and between phenanthroline ligands, with a centroid-to-centroid distance of 3.484?(2)?Å. O-H?O hydrogen bonding additionally stabilizes the crystal packing. The acetic acid mol-ecules are incorporated in the voids of this arrangement. They exhibit half-occupancy due to disorder around a centre of inversion.

Project description:The title copper coordination polymer, [Cu(3)(C(8)H(4)O(4))(2)(C(8)H(5)O(4))(2)(C(10)H(8)N(2))(2)](n), was synthesized by reacting Cu(NO(3))(2), isophthalic acid and 1,10-phenanthroline under hydro-thermal conditions.

These units are bridged by isophthalate ligands into one-dimensional double-chain coordination polymers which are, in turn, connected by various π-π stacking inter-actions (face-to-face distance ca 3.45 Å) and O-H⋯O hydrogen bonds, forming a three-dimensional supra-molecular network.
