The reaction of CoII(TpivPP) {TpivPP is the dianion of 5,10,15,20-tetrakis[2-(2,2-dimethylpropanamido)phenyl]porphyrin} with an excess of KCN salts and an excess of the 18-crown-6 in chlorobenzene leads to the polymeric title compound catena-poly[[dicyanido-2κ2C-(1,4,7,10,13,16-hexaoxacyclooctadecane-1κ6O){μ3-(2α,2β)-5,10,15,20-tetrakis[2-(2,2-dimethylpropanamido)phenyl]porphyrinato-1κO5:2κ4N,N′,N′′,N′′′:1′κO15}cobalt(III)potassium] dihydrate], {[CoK(CN)2(C12H24O6)(C64H64N8O4]·2H2O}n. The CoIII ion lies on an inversion center, and the contains one half of a [CoIII(2α,2β-TpivPP)(CN)2]− ion complex and one half of a [K(18-C-6]+ counter-ion (18-C-6 is 1,4,7,10,13,16-hexaoxacyclooctadecane), where the KI ion lies on an inversion center. The CoIII ion is hexacoordinated by two C-bonded axial cyanide ligands and the four pyrrole N atoms of the porphyrin ligand. The KI ion is chelated by the six O atoms of the 18-crown-6 molecule and is further coordinated by two O atoms of pivalamido groups of the porphyrin ligands, leading to the formation of polymeric chains running along [011]. In the crystal, the polymeric chains and the lattice water molecules are linked by N—H⋯O and O—H⋯N hydrogen bonds, as well as weak C—H⋯O, O—H⋯π and C—H⋯π interactions into a three-dimensional supramolecular architecture.

To a solution of [CoII(TpivPP)] (Collman et al., 1978) (100 mg, 0.067 mmol) in chlorobenzene (10 mL) was added an excess of 18-crown-6 (150 mg, 0.567 mmol) and potassium cyanide (100 mg, 0.378 mmol). A rapid color change from orange-red to green occurred. The resulting material was crystallized by diffusion of hexanes through the chlorobenzene solution which yields {[K(18-C-6)][CoIII(2α,2β-TpivPP)(CN)2].2H2O}n crystals as synthesis product.
The two hydrogens of the water molecule were found in the difference Fourier map and were included in the
using restraints (O-H = 0.85 (1) Å) with Uiso(H) = 1.2Ueq(O6). Other H atoms attached to C and N atoms were fixed geometrically and treated as riding with C—H = 0.99 Å (methylene), 0.95 Å (aromatic) and 0.98 Å with Uiso(H) = 1.2Ueq(Caromatic, methylene, methyl) and N—H = 0.88 Å with Uiso(H) = 1.2Ueq(N).Data collection: CrysAlis PRO (Agilent, 2012); cell

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

In the Cambridge Structural Database (CSD, Version 5.35; Allen, 2002) there are more than ninety structures of cyano-metalloporphyrins. This large number of structures reflects the importance of this type of compounds. Nevertheless, only one structure of cyano-porphyrin species with a cobalt as central ion is known (Hoshino et al.., 2000). The cyano-cobalt porphyrin derivatives are good model for the B12 vitamin called cobalamin, which is a cobalt porphyrin-like protein responsible, inter alia, of the formation of blood.
We reports herein the crystal structure of the poly[(1,4,7,10,13,16-hexaoxacyclooctadecane)potassium(+)(dicyano)(2α,2β-5,10,15,20-tetrakis[2-(2,2-dimethylpropanamido)-phenyl]porphyrinato-κ4N,N',N'',N''')cobaltate(III) dihydrate] with formula{[K(18-C-6)][CoIII(2α,2β-TpivPP)(CN)2].2H2O}n.
In this complex, the cobalt is coordinated to the four N atoms of the porphyrin ring and the carbons of the two trans cyano axial ligands (Fig. 1).
It has been noticed that there is a relationship between the ruffling of the porphyrinato core and the mean equatorial Co—Np distance; the porphyrinato core is ruffled as the Co—Np distance decreases (Iimuna et al., 1988). Indeed, for the very ruffled structure [CoII(TPP)] (Konarev et al., 2003) the Co—Np bond length value is 1.923 (4) Å while the practically planar porphyrin core of the ion complex [CoIII(OEP)(NO2)2]- (OEP is the dianion of the octaethylporphyrin; Ali et al., 2011) presents a Co—Np distance of 1.988 (2) Å. Therefore, the Co—Np bond length in the title complex [1.9844 (14) Å] is normal for a cobalt planar porphyrin species. It is noteworthy that the related dicyano-cobalt(III) derivative
{[K(18-C-6)H2O]2[(CN)2CoIII(TPP)]}[(CN)2CoIII(TPP)].C7H8 (Hoshino et al., 2000) exhibits a very short Co__Np distance [1.93 (1) Å] which is in accordance with a very ruffled porphyrin core.
The Co—C(cyano) bond length value [1.9129 (18) Å] is very close to that of vitamin B12 (1.92 Å ) (Pratt, 1972). This distances is slightly shorter compared to those of the related dicyano-cobalt species mentioned above [Co—C(CN) = 1.98 (2) Å and 1.94 (2) Å].
The potassium anion is coordinated to the six oxygen atoms of the 18-crown-6 where the K—O bond length values are in the range [2.7505 (13) Å - 2.8633 (13) Å]. This cation is also linked to the oxygen O2 of one pivalamido group of the 2α,2β-TpivPP porphyrin with a K__O2 distance of 2.7789 (15) Å leading to a 1D coordination polymer. One water molecule is linked to the nitrogen atom (N3) of one pivalamido group and the nitrogen N5 of the cyano axial ligand via the two intramolecular hydrogen bonds N3-HN3···O6 [2.966 (3) Å] and O6-H1O6···N5 [2.810 (3) Å].
The crystal packing features weak C—H···π interactions between the 1D polymer chains (Table 1 and Fig. 2).
An interesting phenomenon concerning the structure title compound where the porphyrin starting material is the atropisomer α,α,α,α-TpivPP but the final product contains the 2α,2β-TpivPP atropisomer in the polymer {[K(18-C-6)][CoIII(2α,2β-TpivPP)(CN)2].2H2O}n. This kind of stereoisomerism of the TpivPP porphyrin was mentioned in the literature (Li et al., 2010).
