(μ-Ethane-1,2-diamine-κ2 N:N′)bis[bis(ethane-1,2-diamine-κ2 N,N′)zinc(II)] tetrakis(perchlorate)

چکیده
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 ratio. The cation inter-acts weakly with the anion by N-H⋯O hydrogen bonds, generating a three-dimensional network.

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...

The title compound, [Co(C(2)H(8)N(2))(3)][CoMo(CN)(8)(C(2)H(8)N(2))(2)(H(2)O)]·2H(2)O, is isostructural with the Ni(II) analogue. The Mo(IV) atom is coordinated by eight cyanide ligands, one of which forms a bridge to a Co(II) atom that is itself coordinated by two bidentate ethane-1,2-diamine (en) ligands and one water mol-ecule. Another Co(II) complex, coordinated to three bidentate en ligand...

The structure of the title compound, [Cr(NCS)2(C2H8N2)2]ClO4, has been determined from synchroton data. The asymmetric unit consists of one half of a centrosymmetric Cr(III) complex cation and half of a perchlorate anion with the Cl atom on a twofold rotation axis. The Cr(III) ion is coordinated by the four N atoms of two ethane-1,2-di-amine (en) ligands in the equatorial plane and two N-bound ...

The asymmetric unit of the title compound, [Fe(2)(C(5)H(5))(2)(C(2)H(8)N(2))(CO)(4)](BF(4))(2), contains two half-cations, each located on a center of symmetry, and two tetra-fluorido-borate anions. The iron atoms adopt a three-legged piano-stool geometry. All amine H atoms are involved in N-H⋯F hydrogen bonds, which consolidate the crystal packing along with weak C-H⋯O and C-H⋯F inter-actions.
