Abstract top

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 molecules are deprotonated at the phenol O atom and octahedrally coordinate the CoIII atoms through the azomethine N and phenolate O atoms in a mer configuration. In the crystal, the cations, chloride ions and lattice water molecules are linked by N-H...O, N-H...Cl, O-H...Cl and O-H...O interactions, forming a two-dimensional network parallel to (10-1).

Comment top

Solvatomorphism, sometimes called pseudopolymorphism, deals with crystals formed by the same substance but crystallized with different amounts or types of solvent molecules (Desiraju, 2004; Bernstein, 2005; Nangia, 2006; Brittain, 2012). The propensity of a given molecule towards hydrogen-bond formation with the solvent molecules leads to the formation of solvatomorphs of the parent compound with different packing motifs. Like polymorphism, solvatomorphism is commonly observed in structures of organic compounds and is of great significance in pharmaceuticals and materials.

The title compound is a solvatomorph of the complex bis(salicylideneguanylhydrazino-N,N',O)-cobalt(III) chloride trihydrate (refcode GEMJOY; Chumakov et al., 2006). It was isolated in an attempt to prepare a heterometallic Co/Mn compound with the ligand, HL, that was synthesized from Schiff base formation of 2-hydroxybenzaldehyde with aminoguanidine hydrochloride. Details of the used synthetic approach as well as its applications were given by Chygorin et al. (2012). Remarkably, the related ligand, that was made from Schiff base formation of 2,6-dichloro-4-hydroxybenzaldehyde and aminoguanidine bicarbonate, iself was shown to form two solvated crystalline forms (Gutierrez et al., 2011).

The title compound, [Co(C8H9N4O)2Cl].0.5(H2O), is formed of discrete [CoL2]+ cations, chloride anions and water molecules of crystallizaion. Unlike GEMJOY there are two independent cations in the asymmetric unit of the title compound. Both cations are very similar and have no crystallographically imposed symmetry (Fig. 1). The ligand molecules are deprotonated at the phenol oxygen atom and coordinate to the CoIII atoms through the azomethine N and phenol O atoms in such a way that the CoIII atoms are octahedrally surrounded by two anionic ligands in a mer configuration. The Co–N/O distances (Table 1) fall in the range 1.8863 (8)–1.9290 (8) Å, the trans angles at the metal atoms are equal to 172.24 (4)–176.71 (4)°, the cis angles vary from 82.33 (4) to 94.86 (4)°. The coordination geometries around the CoIII atoms are similar to that found in GEMJOY (Chumakov et al., 2006). The deprotonated ligand molecules adopt an almost planar conformation. In the crystal lattice, the cations, chloride ions, and lattice water molecules are linked together by intermolecular N—H···O, N—H···Cl, O—H···Cl and O—H···O interactions to form a two-dimensional network parallel to (101) (Fig. 2, Table 2).

Experimental top

Cobalt powder (0.03 g, 0.5 mmol), MnCl2.4H2O (0.10 g, 0.5 mmol), HL.HCl (0.21 g, 1 mmol) and methanol (30 ml) were heated to 323–333 K and magnetically stirred for 50 minutes. The resulting red-brown solution was filtered and allowed to stand at room temperature. Dark-red block-shaped microcrystals of the title compound were formed after 6 days. They were collected by filter-suction, washed with dry PriOH and finally dried in vacuo (yield: 25%).

Refinement top

H atoms were placed at idealized positions with a constrained C—H distance of 0.95 and an N—H distance of 0.88 Å and refined as part of riding models. Uiso(H) values were set at 1.2Ueq of the attached atom. Water molecule H atoms were refined with geometries restrained to ideal values. The highest remaining electron density peaks (min, max) are 0.60 Å from Co1, and 0.18 Å from H323, respectively.

Special details top

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.

Water molecule hydrogen atoms were refined with geometries restrained to ideal values.
