چکیده
The asymmetric unit of the title compound, C8H10N6O2, contains one-half mol-ecule, which is completed by a crystallographic center of symmetry. The piperazine ring adopts a chair conformation. In the crystal, weak C-H⋯O inter-actions link the mol-ecules into layers parallel to the bc plane. The crystal packing also exhibits short N⋯N contacts of 3.0467 (16) Å between the terminal diazo N atoms from neighbouring mol-ecules.

In the title salt, C(8)H(16)N(2)O(4) (2+)·2H(2)PO(4) (-)·2H(2)O, the piperazine ring is located around an inversion center and adopts a chair conformation. The dihydrogen phosphate anions and free water mol-ecules are linked via O-H⋯O hydrogen bonds into two-dimensional hydrogen-bonding layers, which are further connected through O-H⋯O and N-H⋯O hydrogen bonds involving the protonated piperazin...
