Crystal structure of magnesium copper(II) bis[orthophosphate(V)] monohydrate
Single crystals of magnesium copper(II) bis-[orthophosphate(V)] monohydrate, Mg1.65Cu1.35(PO4)2·H2O, were grown under hydro-thermal conditions. The crystal structure is formed by three types of cationic sites and by two unique (PO4)(3-) anions. One site is occupied by Cu(2+), the second site by Mg(2+)and the third site by a mixture of the two cations with an Mg(2+):Cu(2+) occupancy ratio of 0.6...

متن کاملCrystal structure of tris(hydroxylammonium) orthophosphate
The crystal structure of the title salt, ([H3NOH](+))3·[PO4](3-), consists of discrete hydroxyl-ammonium cations and ortho-phos-phate anions. The atoms of the cation occupy general positions, whereas the anion is located on a threefold rotation axis that runs through the phospho-rus atom and one of the phosphate O atoms. In the crystal structure, cations and anions are linked by inter-molecular...
متن کاملCrystal structure of strontium dinickel iron orthophosphate
The title compound, SrNi2Fe(PO4)3, synthesized by solid-state reaction, crystallizes in an ordered variant of the α-CrPO4 structure. In the asymmetric unit, two O atoms are in general positions, whereas all others atoms are in special positions of the space group Imma: the Sr cation and one P atom occupy the Wyckoff position 4e (mm2), Fe is on 4b (2/m), Ni and the other P atom are on 8g (2), on...
متن کامل2-Aminopyrimidinium dihydrogen phosphate monohydrate
In the title compound, C(4)H(6)N(3) (+)·H(2)O(4)P(-)·H(2)O, the pyrimidin-ium ring is essentially planar, with an r.m.s. deviation of 0.0016 Å. In the structure, pairs of symmetry-related anions are connected into centrosymmetric clusters via strong O-H⋯O hydrogen bonds forming six-membered rings with an R(2) (2)(6) motif. These clusters are inter-connected via water mol-ecules through OW-H⋯O h...
