چکیده
The title compound, C(16)H(26)N(4) (4+)·2.5ClO(4) (-)·1.5NO(3) (-), is an organic salt in which the cation is a fully protonated tetra-mine. The cation lies on an inversion center and, as a consequence, both benzene rings are parallel. The central chain is found in an all-trans arrangement, a conformation different from that observed in the crystal structure of the non-protonated mol-ecule. The charges are balanced by a mixture of nitrate and perchlorate ions. One site is occupied by an ordered perchlorate ion, while the other contains both nitrate and perchlorate ions, with occupancies of 0.75 and 0.25, respectively. In the crystal, the NH(2) (+) groups of the cation form N-H⋯O hydrogen bonds with the anions. The NH(3) (+) groups also behave as donor groups, allowing the building of chains along [100], alternating cations and disordered anions being connected via N-H⋯O hydrogen bonds.

The centrosymmetric dinuclear cadmium title complex, [Cd(2)(C(6)H(18)N(4))(3)](ClO(4))(4), was obtained by the reaction of N,N'-bis-(2-amino-eth-yl)ethane-1,2-diamine (trien) with Cd(NO(3))(2)·4H(2)O and sodium perchlorate in methanol. The Cd(II) cation is coordinated by four N atoms of a non-bridging trien ligand and by two N atoms of a bridging trien ligand in a slightly distorted octa-hedral...

In the title complex, [Cu(ClO(4))(2)(C(7)H(12)N(2)O)(2)], the Cu(II) ion lies on a crystallographic inversion centre. The coordination sphere around Cu(II) ion can be described as tetragonally distorted octa-hedral with two perchlorate O atoms occupying the apical positions and four N atoms from two N(1)-(2-furyl-methyl)ethane-1,2-diamine ligands in the basal plane.

In the title salt, [Zn(2)(C(2)H(8)N(2))(5)](ClO(4))(4), an ethyl-enediamine mol-ecule bridges two bis-(ethyl-enediamine)-zinc units; the five-coordinate Zn atoms show a trigonal-bipyramidal coordination geometry that is distorted towards square-pyramidal (that of one Zn atom is distorted by 12% and that of the other by 34%). The perchlorate ions are all disordered over two positions in a 1:1 ra...
