Diaquatetrakis(pyridine-2,6-dicarboxylato-kappa2O2,O6)tetrakis(micro-pyridine-3,5-dicarboxylic acid-kappa2N:O)tetracopper(II): a copper complex with tetrameric molecular units.

Crystals of the title tetramer, [Cu4(C7H3NO4)4-(C7H5NO4)4(H2O)2], were synthesized hydrothermally at 433 K. The triclinic structure consists of tetrameric molecular species, which interact via strong hydrogen bonds. The Cu(II) ions are distributed equally between one square-pyramidal site and one octahedral site distorted by the Jahn-Teller effect.

CsMoO2(HO3P-CH2-PO3): a new metallodiphosphonate with a hybrid framework.

Crystals of caesium molybdenomethylenediphosphonate, [CsMoO(2)(CH(3)O(6)P(2))], were hydrothermally synthesized at 473 K. The monoclinic structure, as determined from single-crystal X-ray diffraction, is two-dimensional and consists of stacked mixed layers of corner-sharing tetrahedral diphosphonate groups and MoO(6) octahedra, between which Cs+ cations are intercalated.

Beta-Sm(OH)2Cl: a new lamellar variety.

Crystals of dihydroxysamarium chloride were synthesized hydrothermally at 473 K. The orthorhombic structure was determined by single-crystal X-ray diffraction analysis. Beta-Sm(OH)2Cl exhibits a lamellar structure built up from the stacking of neutral slabs; all the atoms lie on crystallographic mirror planes.

Hydrothermal Synthesis, Structure, and Magnetic Properties of a Novel Monodimensional Iron Phosphate: [FeF(HPO(4))(2),N(2)C(3)H(12),(H(2)O)(x)()] (x approximately 0.20) (ULM-14).

ULM-14 or [FeF(HPO(4))(2),N(2)C(3)H(12),(H(2)O)(x)()] (x approximately 0.20) was synthesized by the hydrothermal method (24 h, 453 K) under autogenous pressure. ULM-14 crystallizes in the orthorhombic system (space group Pmca, No.

Hydrothermal Synthesis, Structure, and Solid State (19)F NMR Study of ULM-17: (H(3)O)(2)[V(4)(HPO(4))(PO(4))(3)O(6)F](2)[NC(7)H(14)](6).

(H(3)O)(2)[V(4)(HPO(4))(PO(4))(3)O(6)F](2)[NC(7)H(14)](6) (labeled ULM-17) has been hydrothermally synthesized (150 degrees, 24 h, autogeneous pressure). It is monoclinic (space group P2(1)/c (No. 14)) with a = 21.
