چکیده
In the title compound, [CrF(C(8)H(20)N(4))(H(2)O)](ClO(4))(2)·H(2)O, the Cr atom is in a slightly distorted octa-hedral environment, coordinated by four N atoms of the 4,7-diaza-decane-1,10-diamine ligand, one water mol-ecule and an F atom trans to water. The five-membered chelate ring is in a gauche form, while the two six-membered chelate rings are in chair conformations. The crystal structure is stabilized by several 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...

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 cation of the salt, [Mn(2)(C(14)H(14)N(4))(3)(H(2)O)(2)](ClO(4))(4), lies on a center of inversion, the center lying midway along the ethyl-ene chain of the bridging N,N'-bis-(2-pyridylmethyl-ene)ethane-1,2-diamine ligand. The Mn atom is chelated by two atoms N atoms of this bridging ligand, and is also coordinated by four N atoms of another ligand. The Mn atom is seven-coordinated in a pen...
