abstract: two new transition metal complexes, containing the acidic ligand 5-chlorosalicylic acid (h2l5), and 1,10-phenanthroline（phen） and 1,3-di(4-pyridyl)propane (bpp) as secondary ligands are reported. they are formulated as {[pb(hl5)2(phen)(h2o)]·h2o}n(1), [zn2(hl5)4(bpp)2]n(2). all the complexes are characterized by single-crystal x-ray diffractions. compoud 1 crystallizes in the triclini...

The syntheses of the 4,4′-trimethylenebis(N-methylpiperidine):boric acid (1:1) co-crystal, 4,4′-(1-MeNC5H9)2(CH2)3.B(OH)3 (1), and a zwitterionic tetrahydroxidohexaoxidopentaboron adduct, [B5O6(OH)4(κN-NH2CH2CH2NHEt2).H2O (2), (NH2CH2CH2NEt2 = deen) from appropriate combinatorial libraries primed with B(OH)3, are reported together their spectroscopic (NMR, IR) single-crystal XRD characterizatio...

The polymerization of simple conjugated dienes has long been of interest: polydienes occur throughout Nature, and polyisoprene and its analogues form the basis of entire industries. In contrast, the polymers of similar small conjugated compounds, diacetylenes, trienes, and triacetylenes, are either unknown or laboratory curiosities. For 40 years, the only viable synthetic method for the 1,4-pol...

The magnetic contribution of the Co3+ ions in Co3BO5 has been investigated using Co (K-edge) XMCD, dc susceptibility, and heat capacity measurements. crystal structure single solved detail at T range 296-703 K. results have supplemented by GGA+U calculations.

background: similar to the thermoluminescence (tl) spectra, the optical parameters variations can also be used in tl crystals for dosimetry purposes. these optical parameters can include absorption, transmission and reflection coefficients. materials and methods: single crystals of kbr and kcl which have been used in this research were grown from laboratory grade extra pure precursor powders. c...

The mercury (II) complex, Hg (Meca2en)I2 (1), containing bidentate Schiff base ligand  Meca2en = N,N′-bis[(E)-2-benzylidenepropylidene]ethane-1,2-diamine, has been synthesized and characterized by elemental analyses (CHN) and 1H-NMR spectroscopy. The crystal structure of 1 was determined using single-crystal X-ray diffraction. Structural investigation shows that 1 crystallizes in a monoclinic s...

Single-Crystal Capacitive Sensors In article number 2204065, Min Tu, Rob Ameloot, and co-workers develop a space-confined synthesis method to fabricate surface-embossed micropatterns surface-embedded gold electrodes on metal–organic framework single crystals. A capacitive gas sensor is constructed by embedding Au HKUST-1 flat crystals used for the investigation of ethanol diffusion in pores.

The reaction of [Co2(CO)8] with an equimolar amount the internal alkyne N-(2-butynyl)phthalimide (1-Phthalimido-2-butyne) 1 in heptane solution yields title compound [Co2(CO)6(µ-phthalimidoCH2C≡CMe)] 2. Compound 2 has been characterized using IR, 1H and 13C NMR spectroscopy; tetrahedrane-type cluster framework ascertained a single-crystal X-ray diffraction study performed at 100 K.
