2-Amino-4-methyl­pyrimidinium dihydrogen phosphate

2-Amino-1,3-thia­zolium dihydrogen phosphate

In the title compound, C(3)H(5)N(2)S(+)·H(2)PO(4) (-), the dihydrogen phosphate anions form infinite chains along [001] via short O-H⋯O hydrogen bonds. The 2-amino-thia-zolium cations inter-connect these chains into a three-dimensional network by short linear or bifurcated N-H⋯O and weak C-H⋯O hydrogen bonds.

Lamotriginium dihydrogen phosphate–4-(dimethyl­amino)­benzaldehyde (1/1)

In the title compound, C(9)H(8)Cl(2)N(5) (+)·H(2)PO(4) (-)·C(9)H(11)NO [systematic name: 3,5-diamino-6-(2,3-dichloro-phen-yl)-1,2,4-triazin-2-ium dihydrogen phosphate-4-(dimethyl-amino)-benz-alde-hyde (1/1)], inter-molecular N-H⋯O and O-H⋯O hydrogen bonds produce R(2) (2)(8) and R(3) (2)(8) rings, generating a layer. Inter-molecular N-H⋯N inter-actions also occur. The dihedral angle between the...

2-Amino-3-carb­oxy­pyrazin-1-ium dihydrogen phosphate

In the crystal structure of the title compound, C(5)H(6)N(3)O(2) (+)·H(2)PO(4) (-), the dihydrogen phosphate anions are linked through short O-H⋯O hydrogen bonds, forming infinite double chains running parallel to the b axis. Centrosymetric N-H⋯O hydrogen-bonded cationic dimers form bridges between these chains by means of inter-molecular N-H⋯O and O-H⋯O hydrogen bonds, leading to a two-dimensi...

Investigation of structural mimetics of natural phosphate ion binding motifs.

Phosphates are ubiquitous in biology and nearly half of all proteins interact with their partners by means of recognition of phosphate residues. Therefore, a better understanding of the phosphate ion binding by peptidic structures is highly desirable. Two new receptors have been designed and synthesized and their anion binding properties in an acetonitrile solution have been determined. The str...
