Single crystals of glycine zinc sulfate pentahydrate [systematic name: hexaaquazinc tetraaquadiglycinezinc bis(sulfate)], [Zn(H2O)6][Zn(C2H5NO2)2(H2O)4](SO4)2, have been grown by isothermal evaporation from aqueous solution at room temperature and characterized by single-crystal neutron diffraction. The unit cell contains two unique ZnO6octahedra on sites of symmetry -1 and two SO4tetrahedra with site symmetry 1; the octahedra comprise one [tetraaqua-diglycine zinc]2+ion (centred on one Zn atom) and one [hexaaquazinc]2+ion (centred on the other Zn atom); the glycine zwitterion, NH3+CH2COO−, adopts a monodentate coordination to the first Zn atom. All other atoms sit on general positions of site symmetry 1. Glycine forms centrosymmetric closed cyclic dimers due to N—H...O hydrogen bonds between the amine and carboxylate groups of adjacent zwitterions and exhibits torsion angles varying from ideal planarity by no more than 1.2°, the smallest values for any known glycine zwitterion not otherwise constrained by a mirror plane. This work confirms the H-atom locations estimated in three earlier single-crystal X-ray diffraction studies with the addition of independently refined fractional coordinates andUijparameters, which provide accurate internuclearX—H (X= N, O) bond lengths and consequently a more accurate and precise depiction of the hydrogen-bond framework.

Zinc is an essential micro-nutrients for humans and plants. Zinc on humans is obtained from food, especially rice. This research studied the effect of zinc sulfate heptahydrate spraying application, the effect of zinc sulphate heptahydrate enriched urea application, and the interaction of both, on yield and rice zinc grain concentration in Ciherang varieties. The research was carried out by RCBD. The first factor was without spraying zinc sulfate, spraying 75 g ha-1 zinc sulfate heptahydrate and spraying 150 g ha-1 zinc sulfate heptahydrate. The second factor was without zinc sulfate enriched urea, urea enriched by 7.5 kg ha-1 zinc sulfate heptahydrate, and urea enriched by 15 kg ha-1 zinc sulfate heptahydrate. The parameters observed were grain yield, grain zinc concentration, and rice plant growth. Data were analyzed by analysis of variance at 5% and DMRT test at 5%. The results indicated that spraying 75 g ha-1 zinc sulfate heptahydrate increased yield of rice up to 13%, urea enriched by 7.5 kg ha-1 zinc sulfate heptahydrate increased grain yield zinc concentration up to 33%, Combination of spraying  75 g ha-1 zinc sulfate heptahydrate and urea enriched by 7.5 kg ha-1 zinc sulfate heptahydrate can’t increased the yield and zinc grain concentration.<br /><br />Keywords: rice, urea, zinc, zinc sulfate heptahydrate<br /><br />
