A homologous series of dinuclear compounds with the bridging ligand 2-(2-pyridyl)-1,8-naphthyridine (pynp) has been prepared and characterized by X-ray crystallographic and spectroscopic methods. [Mo(2)(O(2)CCH(3))(2)(pynp)(2)][BF(4)](2) x 3CH(3)CN (1) crystallizes in the monoclinic space group P2(1)/c with a = 15.134(5) A, b = 14.301(6) A, c = 19.990(6) A,(More)
In this paper, an implementation of Low-Density Parity-Check (LDPC) encoder is introduced, which meets the demand of Chinese Digital Terrestrial Multimedia Broadcasting (DTMB) standard. A design of the LDPC encoder which uses a partially-parallel encoding structure based on the Shift Register Adder Accumulator (SRAA) circuit is studied according to the(More)
Novel cobalt phosphonates [Co(H(2)O)(4)(H(4)L)][H(2)L].2H(2)O, 1, and Co(2)(H(2)O)(2)(L), 2, have been synthesized from 1,8-octylenediphosphonic acid (H(4)L). 1 has been fully characterized by X-ray single-crystal data, TGA, IR spectroscopy, and chemical analysis. The compound crystallizes in the triclinic space group P1 with a = 5.5415(8) A, b = 8.6382(8)(More)
Nitrilotris(methylenephosphonic acid) (NTP, [N(CH(2)PO(3)H(2))(3)]) recently has been found to form three-dimensional porous structures with encapsulation of templates as well as layered and linear structures with template intercalation. It was, therefore, of interest to examine the type of organic-inorganic hybrids that would form with metal cations.(More)
The solvothermal reaction of elemental zinc with sulfur in ethylenediamine (en) as solvent yields [ZnS-0.5(NH2CH2CH2NH2)], 1, an unprecedented ethylenediamine pillared ZnS layered compound, containing two dimensional (2-D) boat-type 6-membered rings, which was characterized by ab initio structure solution from powder diffraction data (SDPD).
The title compound poly[[bis(mu-2-carboxylatoethylphosphonato)cadmium] dihydrate], Cd3(O3PC2H4CO2)2.2H2O, was prepared by a hydrothermal reaction and its crystal structure determined from in-house powder data. The structure was solved in both P2(1)/c and P2(1) space groups. The refinement converged with Rp = 0.1046, R(wp) = 0.1378 and Rf = 0.0763 in(More)
Under strictly anhydrous conditions, no reaction occurs between Mo(2)(O(2)CCMe(3))(4) and tetracyanoethylene, TCNE, at room temperature, but after addition of 1 equiv of water, a reaction proceeds to form [Mo(2)(O(2)CCMe(3))(3)((NC)(2)CC(CN)CONH)], 1. The compound contains a quadruple-bonded Mo(2) unit and the 2,3,3-tricyanoacrylamidate anion as a ligand(More)
