چکیده
The asymmetric unit of the title compound, [Co(C(36)H(44)N(4))]·2C(7)H(5)NO(3), is composed of one half of the complex, arranged about an inversion center, and a complete 2-nitro-benzaldehyde (NBA) mol-ecule. The structure consists of columns that contain inter-leaved mol-ecules of NBA and [Co(II)(OEP)] (OEP is 2,3,7,8,12,13,17,18-octa-ethyl-porphyrin), which are stacked along the a axis. The Co(II) atom is involved in a π inter-action with the ring of the NBA mol-ecule with a centroid-metal distance of 3.508 (6) Å. There is an intra-molecular C-H⋯O hydrogen bond in the NBA mol-ecule.

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.

The title compound, [Co(C(2)N(3))(2)(C(3)H(7)NO)(2)](n), is a triclinic polymorph of the previously reported monoclinic structure [Tong et al. (2003 ▶). Acta Cryst. E59, m405-m407]. The Co(II) ion lies on an inversion centre and adopts an almost regular octa-hedral N(4)O(2) coordination geometry. Adjacent Co(II) atoms are connected by two bridging dicyanamide ligands, resulting in the formation...

The title coordination polymer, {[Co(C(18)H(14)O(4))(C(10)H(8)N(2))]·0.5H(2)O}(n), features a helical polymeric chain that runs along the b axis. The Co atoms are chelated by the carboxyl-ate groups of two 3,3'-(but-2-ene-2,3-di-yl)dibenzoate ligands and the N atoms of a 2,2'-bipyridine ligand. The lattice water mol-ecule is disordered about a center of inversion and is connected to the chain b...
