چکیده
The title fluoridogermanate, {[Cd(2)(C(6)H(18)N(4))(3)][GeF(6)]}(n), was synthesized hydro-thermally. The crystal structure comprises undulated cationic [Cd(2)(TETA)(3)](4+) chains (TETA is triethyl-ene-tetra-mine) propagating parallel to [101]. The central Cd(II) atom is six-coordinated in a CdN(6) set by three TETA ligands. The isolated [GeF(6)](2-) units, serving as counter-anions, occupy the inter-chain spaces and simultaneously link adjacent chains into a three-dimensional network through extensive N-H⋯F hydrogen-bonding inter-actions. One of the ethyl-ene bridges of one TETA ligand is disordered around a twofold rotation axis.

In the title compound, [Cd(C(2)N(3))(2)(C(6)H(6)N(2)O(3))(2)](n), the Cd(II) ion (site symmetry ) adopts a distorted trans-CdO(2)N(4) octa-hedral environment, being coordinated by two O-bonded 3-methyl-4-nitro-pyridine N-oxide ligands and four dicyanamide (dca) anions. The bridging dca anions lead to a polymeric chain propagating in [100].

In the crystal structure of the title complex, [Cd(N(3))(2)(C(11)H(11)N(31))(2)](n), there are two crystallographically independent Cd(II) atoms. Both exist in an octa-hedral environment composed of four N atoms of the N(3) (-) groups and two N atoms from two monodentate 1-phenyl-3-(1H-1,2,4-triazol-1-yl)propan-1-one ligands that are positioned trans to each other. Adjacent Cd(II) centres in th...

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 compound, [Cd(2)(C(6)H(8)O(4))(2)(C(16)H(20)N(4))(H(2)O)(4)](n), penta-gonal-bipyramidally coordinated Cd(II) ions are connected into {Cd(2)(2,2-dimethyl-succinate)(2)(H(2)O)(4)} centrosymmetric dimeric clusters. In turn, these clusters are linked by tethering 1,4-bis-(3-pyridylmeth-yl)piperazine (3-bpmp) ligands into [Cd(2)(2,2-dimethyl-succinate)(2)(3-bpmp)(H(2)O)(4)](n) coordina...
