In the crystal structure of the title compound, {(C(5)H(14)N(2))[BiCl(5)]}(n), the Bi(III) cation is coordinated by six Cl(-) anions in a distorted octa-hedral geometry. Two Cl(-) anions bridge neighboring Bi(III) cations, forming a zigzag polymeric chain along the a axis. The discrete methylpiperazinediium cation adopts a normal chair conformation and is linked to the polymeric chains by N-H⋯C...

The title mol-ecule, [Fe(C(36)H(44)N(4))Cl]·1.5CH(2)Cl(2), is a high-spin square-pyramidal iron(III) porphyrinate with an average value for the equatorial Fe-N bond lengths of 2.065 (3) Å and an axial Fe-Cl distance of 2.2430 (13) Å. The iron cation is displaced by 0.518 (1) Å from the 24-atom mean plane of the porphyrin ring. These values are typical for high-spin iron(III) porphyrinates.

In the title complex, [Co(C(15)H(12)N(3)O(4))(2)Cl(C(6)H(7)N)], the Co(III) ion is coordinated by two N atoms and two O atoms from two deprotonated Schiff base ligands, one N atom from a 4-methyl-pyridine ligand and one Cl atom, forming a distorted octa-hedral geometry. The Co(III) ion is displaced by 0.038 (2) Å from the equatorial plane towards the axial Cl atom.

Seven-coordinate, pentagonal-bipyramidal (PBP) complexes [Ln(bbpen)Cl] and [Ln(bbppn)Cl], in which Ln = Tb3+ (products I II), Eu3+ (III IV), Gd3+ (V VI), with bbpen2– N,N′-bis(2-o...

In the title compound, [Fe(C(20)H(14)N(4)O(2))Cl], the Fe(III) ion is in a distorted square-pyramidal environment, with two pyridine and two deprotonated amide N atoms in the basal plane and the Cl ion in the apical position. The Fe(III) ion is displaced from the basal plane of the square- pyramid towards the apical Cl atom by 0.2942 (4) Å. The mol-ecules are linked into a three-dimensional net...

The asymmetric unit of the title complex salt, [Cr(C10H24N4)(NH3)2][ZnCl4]Cl·H2O, is comprised of four halves of the Cr(III) complex cations (the counterparts being generated by application of inversion symmetry), two tetra-chlorido-zincate anions, two chloride anions and two water mol-ecules. Each Cr(III) ion is coordinated by the four N atoms of the cyclam (1,4,8,11-tetra-aza-cyclo-tetra-deca...
