A novel 3D porous metal-organic framework based on trinuclear cadmium clusters as a promising luminescent material exhibiting tunable emissions between UV and visible wavelengths.

With the aim of developing new 1D platinum chain solids having infinite Pt−Pt bonds, several carboxylate-bridged cis-diammineplatinum dimers have been prepared and structurally characterized. For a dimer doubly bridged with acetates, five different salts [Pt2(NH3)4(μ-CH3CO2)2]X2·nH2O (X2, n = (ClO4)2, 2, 1; (NO3)2, 1, 2; (BF4)2, 4, 3; (PF6)2, 2, 4; (SiF6), 4, 5) have been prepared. The crystal structure of 5 has revealed that an infinite dimer chain [Pt2(NH3)4(μ-CH3CO2)2]n2n+ can be given as a result of hydrogen bond formation between the ammines and the oxygen atoms of acetates, demonstrating our prediction that the N2O2 coordination sphere may serve as a hydrogen-bonding moiety to assist formation of an infinite dimer chain. An asymmetric dimer bridged by both acetate and hydroxide ligands, [Pt2(NH3)4(μ-CH3CO2)(μ-OH)](SiF6) (6), has also been isolated as a byproduct of 5, and a similar 1D framework, [Pt2(NH3)4(μ-CH3CO2)(μ-OH)]n2n+, has been characterized by X-ray diffraction. In addition, some glycolate...

A New One-Dimensional Platinum System Consisting of Carboxylate-Bridged cis-Diammineplatinum Dimers1

Thin films of LaB6 are prepared by a radio frequency (rf) magnetron sputtering technique. The effect of sputtering conditions on the film properties of internal stress and crystalline orientation are investigated. The film deposited at low pressures (<1 Pa) has a strong compressive stress as high as 109 Pa. As the pressure of Ar discharge gas decreases, the internal stress becomes greater and the preferred orientation is transformed in the sequence: (100)→(110)→(111). This behavior can be explained as an energetically favorable structure of LaB6 film by taking both the surface energy and the strain energy into account. An application of a negative bias (−20 V) to substrates results in a greater stress, so that the (110) and (111) orientation becomes more preferential.
