Inclusion of potassium 4,4 biphenyldicarboxylate into beta-cyclodextrin: the design and synthesis of an organic secondary building unit Abstract The paper describes a design strategy for the preparation of a novel inclusion compound (potassium 4,4′-biphenyldicarboxylate⊂β-CD) suitable for use in supramolecular chemistry. In the first step the chemical feasibility of such an inclusion compound was evaluated by…
Chemistry and Catalytic Activity of Molybdenum(VI)-Pyrazolylpyridine Complexes in Olefin Epoxidation. Crystal Structures of Monomeric Dioxo, Dioxo-mu-oxo, and Oxodiperoxo Derivatives. Abstract The dioxomolybdenum(VI) complexes [MoO2Cl2(PzPy)] (1) and [MoO2(OSiPh3)2(PzPy)] (5) (PzPy = 2-[3(5)-pyrazolyl]pyridine) were synthesized and characterized by vibrational spectroscopy, with assignments being supported by DFT calculations. Complex 5 was additionally characterized by single crystal X-ray diffraction….
(R)-(1-Ammonioethyl)phosphonate Abstract The title compound, C(2)H(8)NO(3)P, crystallizes in its zwitterionic form H(3)N(+)CH(CH(3))PO(O(-))(OH). In the crystal, the molecules are linked by N-H center dot center dot center dot O and O-H center dot center dot center dot O hydrogen bonds. Fernandes Jose A.; Paz Filipe A.

Hydrogen bond dynamics of C–H•••O interactions: the chloroform–acetone case. Abstract Spectroscopic evidence for C-H…O hydrogen bonding in chloroform…acetone [Cl(3)CH…O=C(CH(3))(2)] mixtures was obtained from vibrational inelastic neutron scattering (INS) spectra. Comparison between the INS spectra of pure samples and their binary mixtures reveals the presence of new bands at about 82, 130 and 170 cm(-1). Assignment…
Tetrapyridinium mu-oxido-di-mu-sulfato-bis[chloridodioxidomolybdate(VI)]. Abstract The title salt, (C(5)H(6)N)(4)[Mo(2)Cl(2)O(5)(SO(4))(2)], comprises four pyridinium cations for each [(MoClO(2))(2)(mu-O)(mu-SO(4))(2)]4- anionic unit. The asymmetric unit consists of three aggregates of the empirical formula. The tetraanionic bimetallic molybdenum(VI) cluster is unprecedented and contains two sulfate and one oxide bridges. This structure constitutes the first example of a non-polymeric compound with terminal oxide,…
