Poly[aqua-(?(3)-2-hy-droxy-5-nitro-benzoato-?O:O:O)rubidium].

ABSTRACT: In the structure of title compound, [Rb(C(7)H(4)NO(5))(H(2)O)](n), the centrosymmetric cyclic dimeric repeating unit comprises two irregular RbO(4) complex centres bridged by the carboxyl-ate groups of the 5-nitro-salicylate ligands. The coordination about each Rb atom is completed by a monodentate water mol-ecule and a phenolic O-atom donor which gives a bridging extension [Rb-O range = 3.116?(7)-3.135?(5)?Å]. The polymeric structure is stabilized by inter-molecular water O-H?O(carboxyl-ate) hydrogen bonds and weak inter-ring ?-? inter-actions [minimum ring centroid separation = 3.620?(4)?Å]. An intramolecular O-H?O hydrogen bond between phenol and carboxylate groups is also present.

Poly[bis-(?-2-amino-4-nitro-benzoato)di-?-aqua-dirubidium].

Project description:In the structure of the title salt, [Rb2(C7H5N2O4)2(H2O)2] n , the asymmetric unit comprises two independent and different seven-coordinate Rb(+) cations, one forming an RbO7 polyhedron, the other a RbO6N polyhedron, each of which is considerably distorted. The RbO7 polyhedron comprises bridging O-atom donors from two water mol-ecules, three carboxyl-ate groups, and two nitro groups. The RbO6N polyhedron comprises the two bridging water mol-ecules, one monodentate amine N-atom donor, one carboxyl O-atom donor and three O-atom donors from nitro groups (one from the chelate bridge). The extension of the dinuclear unit gives a three-dimensional polymeric structure which is stabilized by both intra- and inter-molecular amine N-H?O and water O-H?O hydrogen bonds to carboxyl and water O-atom acceptors, as well as a number of inter-ring ?-? inter-actions [minimum centroid-centroid separation = 3.364?(2)?Å]. The title salt is isostructural with the analogous caesium salt.

Project description:In the crystal of the title polymeric compound, {[Pb(C(7)H(5)O(3))(2)(C(6)H(6)N(2)O)]·H(2)O}(n), the Pb(II) ion is chelated by two carboxyl-ate groups of 3-hy-droxy-benzoate (HB) anions, and coordinated by one isonicotinamide mol-ecule; a carboxyl-ate O atom and a hy-droxy O atom from adjacent HB anions bridge the Pb(II) ion to form polymeric chains along [100], in which the Pb(II) ion is in an irregular seven-coordination geometry. The carboxyl-ate groups of the HB ions are slightly twisted away from the attached benzene rings by 2.84?(15) and 4.8?(2)°. The planes of the two benzene rings of the HB ions are oriented with respect to each other at a dihedral angle of 84.41?(8)°. In the crystal, adjacent polymeric chains inter-act via O-H?O, N-H?O and weak C-H?O hydrogen bonds. The solvent water mol-ecule links with the polymeric chains via O-H?O hydrogen bonding. ?-? stacking between the benzene and pyridine rings and between the benzene rings [centroid-centroid distances = 3.731?(2) and 3.353?(2)?Å] are present in the crystal.

Project description:In the title compound, [Pb₂(C₇H₄O₆S)₂(C₁₂H₈N₂)₂(H₂O)₂]·CH₃COOH, 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 π-π 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.

Poly[di-?-aqua-bis-(?-2-amino-4-nitro-benzoato)dicaesium].

Project description:In the structure of title compound, [Cs(2)(C(7)H(5)N(2)O(4))(2)(H(2)O)(2)](n), the asymmetric unit contains two independent Cs atoms comprising different coordination polyhedra. One is nine-coordinate, the other seven-coordinate, both having irregular configurations. The CsO(9) coordination polyhedron comprises O-atom donors from three bridging water mol-ecules, one of which is doubly bridging, three from carboxyl-ate groups, and three from nitro groups, of which two are bidentate chelate bridging. The CsO(6)N coordination polyhedron comprises the two bridging water mol-ecules, one amine N-atom donor, one carboxyl-ate O-atom donor and four O-atom donors from nitro groups (two from the chelate bridges). The extension of the dimeric unit gives a three-dimensional polymeric structure, which is stabilized by both intra- and inter-molecular amine N-H?O and water O-H?O hydrogen bonds to carboxyl-ate O-atom acceptors, as well as inter-ring ?-? inter-actions [minimum ring centroid-centroid separation = 3.4172?(15)?Å].
