چکیده
In the structure of the title compound, CH(6)N(3) (+)·C(6)H(6)AsO(3) (-)·CH(5)N(3)·2H(2)O, the phenyl-arsonate anion participates in two R(2) (2)(8) cyclic hydrogen-bonding inter-actions, one with a guanidinium cation, the other with a guanidine mol-ecule. The anions are also bridged by the water mol-ecules, one of which completes a cyclic R(5) (3)(9) hydrogen-bonding association with the guanidinum cation, conjoint with one of the three R(2) (2)(8) associations about that ion, as well as forming an R(2) (1)(6) cyclic association with the guanidine mol-ecule. The result is a three-dimensional framework structure.

In the structure of the title hydrated salt, 2CH(6)N(3) (+)·C(8)H(2)Cl(2)O(4) (2-)·H(2)O, the planes of the carboxyl-ate groups of the dianion are rotated out of the plane of the benzene ring [dihedral angles = 48.42 (10) and 55.64 (9)°]. A duplex-sheet structure is formed through guanidinium-carboxyl-ate N-H⋯O, guanidinium-water N-H⋯O and water-carboxyl-ate O-H⋯O hydrogen-bonding associations.

The asymmetric unit of the title salt, C10H20N3O2 (+)·C24H20B(-), contains two cations and two tetra-phenyl-borate ions. The C-N bond lengths in the central CN3 unit of the guanidinium ions range between 1.323 (2) and 1.381 (2) Å, indicating partial double-bond character. The central C atoms are bonded to the three N atoms in a nearly ideal trigonal-planar geometry and the positive charge is de...
