Arthropods are an important group of macroorganisms that work to maintain ecosystem health. Despite the agricultural benefits of chemical control against arthropod pests, insecticides can cause environmental damage. We examined the effects of one and two applications of the insecticides chlorfenapyr (0.18 liters a.i. ha-1) and methamidophos (0.45 liters a.i. ha-1), both independently and in com...

The title compound, C(19)H(30)O(9), was prepared by substitution at the C6 position in 1,2;3,4-di-O-isopropyl-idene-6-O-trifluoro-methane-sulfonyl-d-galactose using sodium eth-oxy-malonate in dimethyl-formamide. The conformation is skew-boat (0)S(2), slightly distorted towards boat B(2,5). The inflexible pyran-ose structure makes the title compound a suitable inter-mediate for further synthetic...

The title complex, [Mg(C7H7N4O2)2(H2O)4], lies across an inversion centre and the Mg(II) atom is coordinated in a slightly distorted octa-hedral environment by four aqua ligands in the equatorial sites and two 1,3-dimethyl-2,6-dioxo-3,7-di-hydro-1H-purin-9-ide ligands, through imidazole ring N atoms, in the axial sites. An intra-molecular O-H⋯O hydrogen bond forms an S(7) graph-set motif. In th...

The title mol-ecule, C8H12NO5PS2, exhibits a crystallographic mirror plane that is perpendicular to the ring and bis-ects the sulfamoyl and thio-phosphate ester groups. In the crystal, mol-ecules are linked by N-H⋯O hydrogen-bonding inter-actions reminiscent of carb-oxy-lic acid hydrogen bonding pairs, forming chains parallel to the b-axis direction.

The asymmetric unit of the title compound, [Ni(C(15)H(11)N(4)OS)(2)]·C(3)H(7)NO, contains one Ni(II) complex mol-ecule and one disordered dimethyl-formamide solvent mol-ecule. The Ni(II) ion is six-coordinated in a distorted octa-hedral geometry by two N, two O and two S atoms. An intra-molecular C-H⋯S hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked through int...

An efficient and general method for the synthesis of reduced polypropionates has been developed through the application of asymmetric carboalumination of alkenes catalyzed by dichlorobis(1-neomenthylindenyl)zirconium [(NMI)(2)ZrCl(2)]. In this investigation, attention has been focused on those reduced polypropionates that are alpha-monoheterofunctional and either omega-ethyl or omega-n-propyl. ...

The title complex, [Ni(C(24)H(32)N(4))](C(14)H(14)O(2)PS(2))(2), comprises a centrosymmetric [Ni(meso-diphen-yl[14]dien)](2+) dication (meso-diphen-yl[14]dien is C-meso-N-meso-5,12-dimethyl-7,14-diphenyl-1,4,8,11-tetra-aza-cyclo-tetra-deca-4,11-diene) and two O,O'-bis-(4-methyl-phen-yl) dithio-phosphate anions. The Ni(II) ion lies on an inversion center and is chelated by a tetra-amine macrocyc...

The asymmetric unit of the title compound, [Pt(C(5)H(4)NOS)Cl(C(2)H(6)OS)], contains two independent complex mol-ecules having similar geometries. Each Pt(II) atom is four-coordinated in a distorted square-planar geometry by S and O atoms of one pyridine N-oxide ligand, the S atom of one dimethyl sulfoxide mol-ecule and one terminal Cl(-) ion. The mol-ecules are linked into a three-dimensional ...

The title compound, C(16)H(12)N(2)O(6)·2C(3)H(7)NO, lies across a crystallographic inversion centre which is situated at the midpoint of the central N-N bond. The substitution at the C=N bond adopts a trans configuration and it is essentially coplanar with the benzene ring [N-C-C-C torsion angles = -173.9 (4) and 6.4 (6)°]. All torsion angles involving non-H atoms are close to 180°. Intra-molec...
