چکیده
In the title compound, Na(3)(C(6)H(15)N(5)O)(2)[Al(OH)(6)Mo(6)O(18)](2)Cl·20H(2)O, the [Al(OH)(6)Mo(6)O(18)](3-) polyoxo-anion has a B-type Anderson structure exhibiting approximate D(3d) symmetry. There are two types of sodium cations: the Na(+) cations of type I have a distorted octa-hedral coordination geometry formed by six O atoms and are statistically distributed over two positions with equal occupancies, while the coordination polyhedra of the two Na(+) cations of type II share one Cl anion located on an inversion center. The latter fragment, containing a Cl anion and two sodium cations, links two polyoxoanions into centrosymmetric blocks. The diprotonated 1-[imino-(morpholino)meth-yl]guanidinium cations and uncordinated water mol-ecules contribute to extensive N-H⋯O and O-H⋯O hydrogen bonding, resulting in the formation a three-dimensional supra-molecular structure.

Crystal structures of the three closely related compounds: bis[(1H-tetrazol-5-yl)methyl]nitramide, triaminoguanidinium 5-({[(1H-tetrazol-5-yl)methyl](nitro)amino}methyl)tetrazol-1-ide, and diammonium bis[(tetrazol-1-id-5-yl)methyl]nitramide monohydrate
In the mol-ecule of neutral bis-[(1H-tetra-zol-5-yl)meth-yl]nitramide, (I), C4H6N10O2, there are two intra-molecular N-H⋯O hydrogen bonds. In the crystal, N-H⋯N hydrogen bonds link mol-ecules, forming a two-dimensional network parallel to (-201) and weak C-H⋯O, C-H⋯N hydrogen bonds, and inter-molecular π-π stacking completes the three-dimensional network. The anion in the molecular salt, tri-am...

In the title compound, [Ag(2)(C(14)H(14)N(4))(2)](C(14)H(8)N(2)O(4))·2H(2)O, each of the two unique Ag(+) ions is two-coordinated by two N atoms from two different 1,4-bis-[(imidazol-1-yl)meth-yl]benzene ligands in an almost linear fashion [N-Ag-N = 170.34 (10) and 160.25 (10)°]. The 4,4'-diazenediyldibenzoate anions do not coordinate to Ag. O-H⋯O hydrogen bonds stabilize the crystal structure.
