Reddish-orange single crystals of hexaamminecobalt(III) chloride selenate trihydrate, [Co(NH3)6]ClSeO4· 3H2O, have been prepared by reacting aqueous solutions and potassium in a 1 : molar ratio. The salt was characterized elemental analyses, thermogravimetry, magnetic moment spectroscopic studies (IR, electronic). A crystal X-ray structure determination revealed that the title complex crystallizes orthorhombic space group Pnma with = 18.230(2), b 8.591(2), c 8.593(2) Å, V 1345.9(4) Å3, Z 4,...
Orange, single crystals of the bimetallic salt hexaamminecobalt(III) chloride molybdate trihydrate, [Co (NH3)6]ClMoO4·3H2O, have been prepared by reacting hot aqueous solutions and sodium dihydrate in a 1:1 molar ratio. The was characterized elemental analyses spectroscopic studies (IR electronic). title complex crystallizes orthorhombic, space group Pnma, with = 18.408(2), b 8.672(1), c 8.661(1) Å, V 1382.6(3) Å3, Z 4 R 0.0255.

Orange-colored single crystals of hexaamminecobalt(III) chloride dichromate monohydrate, [Co(NH3)6]ClCr2O7·H2O, were prepared by reacting hot aqueous solutions and potassium in a 1:1 molar ratio allowing the mixture to cool slowly room temperature. The salt was characterized elemental analyses spectroscopic studies. A single-crystal X-ray structure determination revealed that crystallizes space group P21/c with = 10.0218(9), b 9.3216(8), c 16.2203(13) Å, β 112.962(6)°, V 1395.2(2) Å3, Z 4 R...
Sporadic rainfall and limited surface water sources have increased dependency on groundwater in semi-arid region of Punjab. The present paper is comprehensive study carried out an intensive agricultural southwest Punjab to examine the quality extent contamination due trace elements nitrate aquifer system. Total 15 toxic are analyzed samples (N = 129) covering both shallow (<60 m) deeper aquifers (>60 m). Elements such as As, B, Cd, Li, Mn, Pb, Sr, Se exceed prescribed limits. Overall, 68 13%...
The reaction of hexaamminecobalt(III) chloride with sodium azide and potassium selenocyanate (1 ∶ 3 molar ratio) in hot aqueous medium leads to formation reddish-orange crystals composition [Co(NH3)6]Cl2SeCN (1) [Co(NH3)6]3Cl4(N3)5 (2), respectively. Single crystal X-ray structural analysis 1 2 reveals the supramolecular hydrogen bonding network between ionic groups (i.e. SeCN− or N3− Cl−) atom coordinated NH3 molecules leading 'rings' (in 1) 'rectangles' 2) ions their respective lattices....
