in order to study the effects of micronutrients application on some morphological traits associated with seed quantity and quality of sugar beet cultivar shirin, an experiment was conducted in 2001-02 at ardabil agricultural research station. based on soil test results, soil ph was 7.62-7.80 with 0.49- 0.53% organic matter content, and the quantity of absorbable p, total n, and k amounts were f...

In the title compound, [Mn(C(8)H(8)N(3)O(3)S(2))(2)(H(2)O)(4)], the Mn(II) atom (site symmetry ) adopts a slightly distorted octa-hedral MnO(6) geometry. The mol-ecular conformation is supported by N-H⋯N and O-H⋯O hydrogen bonds. In the crystal, mol-ecules inter-act by O-H⋯O, O-H⋯S, N-H⋯O and N-H⋯S hydrogen bonds, thereby forming (011) sheets.

In the title complex, [Mn(CHO(2))(C(12)H(8)N(2))(2)]ClO(4), the Mn(II) cation is chelated by two 1,10-phenanthroline (phen) ligands and one formate anion in a distorted MnN(4)O(2) octa-hedral geometry. The two phen planes are oriented at a dihedral angle of 57.48 (11)°. The perchlorate anion links with the Mn complex cation via weak C-H⋯O hydrogen bonding.

The title compound, [Mn(C(8)H(4)N(8))(2)(H(2)O)(5)]·2H(2)O, is the fourth transition metal complex containing the 1,3-di(2H-tetra-zol-5-yl)benzene ligand to be structurally characterized. The Mn^II^ cation has a distorted octahedral coordination geometry. The 1,3-di(tetra-zol-5-yl)benzene ligand is planar. All H atoms bonded to O atoms participate in hydrogen bonds, which link the mol-ecules in...

In the crystal structure of the title compound, [Mn(NO(3))(2)(C(12)H(8)N(2))](n), the Mn(II) atoms are linked by nitrate ligands to form a chain. Each Mn(II) atom is five-coordinated by two N atoms of a 1,10-phenanthroline ligand and three O atoms of two nitrates within a trigonal-bipyramidal coordination geometry. In the crystal structure, the chains are linked by hydrogen bonds into a polymer...

Objective(s):   Recently, applications of MnO2 nanoparticles and microparticles in industry, pharmacology, and medicine have considerably expanded. Mn distribution and clearance from brain and spinal cord tissue compared with muscle tissue of rats after single subcutaneous injection of nanoparticles and microparticle of MnO2. Pain sensory threshold of rat was evaluated as neurologic consequence...

Treatment of [HNBu3]3[Mo(V)(CN)8] with manganese(II) p-toluenesulfonate in N,N'-dimethylformamide (DMF) affords {[Mn(II)(DMF)4]3[Mo(V)(CN)8]2}n (1) as a two-dimensional network. The structure of 1 consists of [cis-Mn(II)(DMF)4(mu-NC)2]2+ and [trans-Mn(II)(DMF)4(mu-NC)2]2+ units that are linked via cyanides to three-connected [Mo(V)(CN)5(mu-CN)3]3- centers in a 4:2:6 ratio, forming 12-membered r...
