The title complex, [Cd(C9H7O2)2(H2O)2], was obtained as an unintended product of the reaction of cadmium nitrate with hexa-methyl-ene-tetra-mine and cinnamic acid. The Cd(II) ion lies on a twofold rotation axis and is coordinated in a slightly distorted trigonal-prismatic environment. In the crystal, the V-shaped mol-ecules are arranged in an inter-locking fashion along [010] and O-H⋯O hydrogen...

highly crystalline bi3+-doped cadmium oxide (cdo) sub-micron structures were synthesized by calcination the obtained precursor from a sol-gel reaction. the reaction was carried out with cadmium nitrate (cd(no3)2.4h2o), bismuth nitrate (bi(no3)3.5h2o) and ethylene glycol (c2h6o2) reactants without any additives at 80°c for 2h. resulting gel was calcined at 900 °c with increasing temperature rate...

The reaction of cadmium nitrate and sodium nitrite in the presence of 1,10-phenanthroline yields the mixed nitrate-nitrite title complex, [Cd(NO(2))(1.75)(NO(3))(0.25)(C(12)H(8)N(2))(2)]. The metal ion is bis-chelated by two N-heterocycles as well as by the nitrate/nitrite ions in a distorted dodeca-hedral CdN(4)O(4) coordination environment. One nitrite group is ordered; the other is disordere...

a pot experiment was designed to evaluate the effect of trichoderma spp. on yield and yield components of wheat (cv. n81) under different levels of cadmium nitrate. experiment was arranged in factorial based on completely randomized design with three replicates. trichoderma harzianum at two levels (with and without inoculation) and four levels of cadmium nitrate (0, 50, 100, 150 mg l-1) were th...

Sumarry. In wheat seedlings (Triticum durum), uptake of potassium and nitrate, transpiration and shoot growth were inhibited by adding cadmium to the nutrient medium. A sharp reduction in cytokinin content was observed within two hours of supplying cadmium. The reduction in cytokinin content was probably a result of hormone breakdown. In support of this, Cd-treatment elevated cytokinin oxidase ...

Nitrate determination in waters is generally carried out with cadmium filings and carcinogenic reagents or by reaction with phenolic compounds in highly concentrated sulfuric acid medium. In this work, it was developed a green analytical procedure for nitrate determination in natural waters based on direct spectrophotometric measurements in ultraviolet, using a flow-injection system with an ani...

A simple and sensitive flow injection spectrophotometric method is reported for the room temperature determination of nitrite and nitrate based on the Griess reaction and a copperised cadmium column for reduction of nitrate. Calibration graphs were linear over the range 2 – 1000 μg N L (R = 0.9997 and 0.9999, n = 9) with a limit of detection (3 s.d.) of 1.0 μg N L and relative standard deviatio...

A novel spectrophotometric reaction system was developed for the determination of nitrite as well as nitrate in water samples, and was applied to a flow-injection analysis (FIA). The spectrophotometric flow-injection system coupled with a copperised cadmium reductor column was proposed. The detection was based on the nitrosation reaction between nitrite ion and phloroglucinol (1,3,5-trihydroxyb...

Nitrate reallocation to plant roots occurs frequently under adverse conditions and was recently characterized to be actively regulated by Nitrate Transporter1.8 (NRT1.8) in Arabidopsis (Arabidopsis thaliana) and implicated as a common response to stresses. However, the underlying mechanisms remain largely to be determined. In this study, characterization of NRT1.5, a xylem nitrate-loading trans...

The title compound, [Cd(NO(3))(C(5)H(8)N(2))(4)]NO(3), was prepared by reaction of cadmium nitrate and 3,5-dimethyl-pyrazole in ethanol solution. The Cd atom adopts a distorted cis-CdO(2)N(4) octa-hedral geometry involving four dimethylpyrazole molecules and one bidentate nitrate anion. The mol-ecular structure and packing are stabilized by N-H⋯O and C-H⋯O inter- and intra-molecular hydrogen-bo...
