Poly[[diaqua-bis(?(2)-isonicotinato-?N:O)bis-(?(3)-isonicotinato-?N:O:O')neodymium(III)disilver(I)] nitrate monohydrate].

ABSTRACT: In the title complex, {[Ag(2)Nd(C(6)H(4)NO(2))(4)(H(2)O)(2)]NO(3)·H(2)O}(n), the Nd(III) ion is coordinated by eight O atoms from six isonicotinate ligands and two water mol-ecules in a distorted square anti-prismatic geometry. Each Ag(I) ion is coordinated by two N atoms from two different isonicotinate ligands. The crystal structure exhibits a two-dimensional heterometallic polymeric layer. O-H?O hydrogen bonds involving the coordinated and uncoordinated water mol-ecules and intra-layer ?-? inter-actions between the pyridine rings [centroid-centroid distances = 3.571?(2) and 3.569?(2)?Å] are observed. Each layer inter-acts with two neighboring ones via Ag?O(H(2)O) contacts and inter-layer ?-? inter-actions [centroid-centroid distances = 3.479?(3) to 3.530?(3)?Å], leading to a three-dimensional supra-molecular network.

Project description:In the title compound, {[Ag(2)Gd(C(6)H(4)NO(2))(4)(H(2)O)(2)]NO(3)·H(2)O}(n), the Gd(III) ion is coordinated by eight O atoms from six isonicotinate ligands and two water mol-ecules in a distorted square anti-prismatic geometry.

These metal ions are connected by the isonicotin-ate ligands into a layer parallel to (010). O-H?O hydrogen bonds donated by the coordinated and uncoordinated water mol-ecules and intra-layer ?-? stacking inter-actions between the pyridine rings [centroid-centroid distances = 3.551?(4) and 3.555?(4)?Å] are observed.

Project description:In the title complex, {[Tb(C(6)H(5)NO(2))(3)(H(2)O)(2)](ClO(4))(3)·H(2)O}(n), the Tb(III) ion is coordinated by six O atoms from six isonicotinate (inic) ligands and two water mol-ecules, displaying a bicapped trigonal-prismatic geometry. The inic ligands, which are protonated at the pyridine N atom, link the metal centres, forming a polymeric chain running parallel to the a axis. The chains are further assembled via intra- and inter-molecular O-H?O and N-H?O hydrogen-bonding inter-actions into a three-dimensional supra-molecular network involving the inic ligands, the water mol-ecules and the perchlorate anions. One of the perchlorate ions is disordered over two sites with occupancies of 0.561?(17) and 0.439?(17).

Poly[[diaqua-?(3)-citrato-praseodymium(III)] monohydrate].

Project description:In the coordination polymer, {[Pr(C(6)H(5)O(7))(H(2)O)(2)]·H(2)O}(n), seven of the nine coordination sites of the monocapped square-anti-prismatic geometry are occupied by three O atoms of the same citrate trianion (an O atom of the hy-droxy unit and the formally single-bond O atoms from two carboxyl units). Two other coordination sites are occupied by the O atoms of a chelating carboxyl unit of another citrate; one of these atoms is additionally involved in bridging. The seventh coordination site is occupied by the O atom of the formally double-bond O atom of a neighboring citrate. The remaining two coordination sites are occupied by water mol-ecules. The citrate functions in a ?(3)-bridging mode, connecting the metal atoms into a ribbon structure parallel to [010]. The structure is consolidated into a three-dimensional network by O-H?O hydrogen bonds.
