چکیده
The crystal structure of the title compound, [Rh(C(6)H(19)N(4))Cl(3)]Cl·0.5H(2)O, is isotypic with the previously reported Ru analogue. The structure contains two crystallographically independent [Rh(Htren)Cl(3)](+) cations with a facial tridentate coordination of the monoprotonated tren ligand [tren = tris-(2-amino-eth-yl)amine], leading to an overall distorted octahedral coordination environment around the Rh(III) atom. In one of the two cations, the ethyl-ene groups of the two chelate rings as well as the non-coordinating ethyl-ammonium group are disordered over two sets of sites [0.579 (3):0.421 (3) occupancy ratio]. A series of N-H⋯Cl and O-H⋯Cl hydrogen bonds stabilizes the structure.

In the title compound, C(6)H(19)N(4) (+)·Cl(-)·CH(2)Cl(2), the non-H atoms of the ammonium ion show non-crystallographic C(3) symmetry. The chloride ion is embedded in a framework of seven crystallographically independent hydrogen bonds (five N-H⋯Cl and two C-H⋯Cl), which form layers parallel to the (100) plane. Two N---H...N bonds also occur.

In the title compound, [Mn(C(20)H(14)N(2)O(2))(N(3))(H(2)O)]·0.5H(2)O, the Mn(III) ion is chelated by the N,N',O,O'-tetra-dentate Schiff base ligand and further coordinated by one azide ion and one water mol-ecule in trans positions, resulting in a distorted fac-MnN(3)O(3) octa-hedral arrangement. The O atom of the uncoordinated water mol-ecule lies on a crystallographic twofold axis. In the cr...

The title compound, [Co(C8H9N4O)2]Cl·0.5H2O, is a solvatomorph of the corresponding trihydrate. Unlike in the structure of the latter compound, there are two different cations in the asymmetric unit of the title compound. The ligand mol-ecules are deprotonated at the phenol O atom and octa-hedrally coordinate the Co(III) atoms through the azomethine N and phenolate O atoms in a mer configuratio...

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...
