The structure of the condensed bromocadmate anions in [C(NH2)3]Cd2Br5 (1) and [H2NNH3]3CdBr5 (2) were studied at room temperature by X-ray diffraction. (1) crystallizes with double-chains bridged by Br atoms (orthorhombic, Pmmn, Z = 2, a = 1394.0(5), b = 394.5(1), c = 1086.9(5) pm). This chain structure was not described previously. (1) shows three 8 'Br NQR lines at temperatures between 77 and...

The two-body decays of the extra neutral boson Z2 predicted by the minimal 331 model are analyzed. At the three-level it can decay into standard model particles as well as exotic quarks and the new gauge bosons predicted by the model. The decays into a lepton pair are strongly suppressed, with Br(Z2 → l+l−) ≈ 10−2 and Br(Z2 → ν̄lν) ≈ 10−3. In the bosonic sector, Z2 would decay mainly into a pair...

In the title compound, C(16)H(12)Br(2)O(6)·C(2)H(5)OH, the two benzene rings are twisted by 80.64 (5)° and the carboxyl groups form dihedral angles of 72.48 (3) and 89.41 (2)° with the corresponding benzene rings. In the crystal structure, the biphenyl mol-ecules are connected by inter-molecular O-H⋯O and O-H⋯Br hydrogen bonds, resulting in a chain along the b axis.

Three novel halogenated organic compounds (HOCs) have been identified in the blubber of marine mammals from coastal New England with the molecular formulae C(9)H(3)N(2)Br(6)Cl, C(9)H(3)N(2)Br(7), and C(9)H(4)N(2)Br(5)Cl. They were identified using high and low resolution gas chromatography mass spectrometry (GCMS) and appear to be highly brominated analogues of Q1, a heptachlorinated HOC suspec...

Seven Zn(II) coordination complexes with 5-halonicotinic acids (HL-X, X = F, Cl, or Br) have been synthesized with different synthetic approaches, including layer diffusion or stirring method in an ambient environment and solvothermal synthesis at 100 °C. Assembly of HL-F with Zn(II) under different conditions will yield the same 2D network of [Zn(L-F)2]n (1). Interestingly, three distinct comp...

Dietary nitrate (NO(3)(-)) supplementation with beetroot juice (BR) over 4-6 days has been shown to reduce the O(2) cost of submaximal exercise and to improve exercise tolerance. However, it is not known whether shorter (or longer) periods of supplementation have similar (or greater) effects. We therefore investigated the effects of acute and chronic NO(3)(-) supplementation on resting blood pr...

In the title compound, [Sb(C(6)H(5))(3)(C(6)H(3)BrNO(2))(2)], the Sb center has a distorted trigonal-bipyramidal geometry, with two carboxyl-ate O atoms of two 5-bromo-pyridine-2-carboxyl-ate ligands in equatorial positions and three phenyl ligands in axial positions. The crystal structure is stabilized by C-H⋯Br hydrogen bonds and inter-molecular C-Br⋯π inter-actions [C⋯π = 3.57 (1) Å].

In the title compound, C(26)H(24)BrN(3)O(5)S, the central benzene ring makes dihedral angles of 6.27 (6), 33.63 (6) and 69.31 (5)°, respectively, with the pyrazolone ring, the bromo-benzene ring and the terminal phenyl ring. An intra-molecular C-H⋯O hydrogen bond occurs. The crystal packing features weak non-classical C-Br⋯O inter-actions [Br⋯O = 3.222 (2) Å] that form inversion-related dimers.

The title compound, C(5)H(4)Br(2)S(4), consists of a statistically planar, 4-bromo-1,3-dithiole-2-thione unit [maximum deviation from the ring plane 0.001 (2) Å], with a bromo-ethyl-sulfanyl substituent in the 5-position. In the crystal structure, weak inter-molecular S⋯S [3.438 (15) and 3.522 (15) Å] and S⋯Br [3.422 (14) and 3.498 (14) Å] inter-actions generate a three-dimensional supra-molecu...
