چکیده
In the title compound, [K(C(18)H(36)N(2)O(6))][Co(NCO)(2)(C(44)H(28)N(4))]·0.5C(6)H(5)Cl or [K(2,2,2-crypt)(+)][Co(III)(NCO)(2)(TPP)(-)]·0.5C(6)H(5)Cl, the Co(III) ion is octa-hedrally coordin-ated by two axial N-bonded NCO(-) anions and four pyrrole N atoms of the porphyrin. There is a major ruffling distortion of the porphyrin: the dihedral angles between trans pyrrole rings are 34.32 (14) and 34.72 (14)°. The potassium ion is coordinated by the six O atoms and two N atoms of the cryptand-222 mol-ecule and a weak K-O [3.407 (3) Å] bond to one of the cyanate O atoms also occurs. The packing also features weak C-H⋯O and C-H⋯π inter-actions. The contribution to the scattering of the disordered chloro-benzene solvent mol-ecules was removed with the SQUEEZE function in PLATON [Spek (2009 ▶). Acta Cryst. D65, 148-155].

The cation, anion, and solvent in the title compound, [K(C(18)H(36)N(2)O(6))][Co(C(8)H(12))(C(16)H(10))(2)]·0.5C(5)H(12), are well separated. The pentane solvent mol-ecules are found in channels along [100] and were modeled as disordered over crystallographic inversion centers. Using the mid-points of the coordinated olefins, the angle between the C(py)/C(py)-Co-C(py)/C(py) and the C(cod)/C(cod...

The reaction of [Co(III)(TPP)Cl] (TPP is the dianion of 5,10,15,20-tetra-phenyl-porphyrin) with an excess of 4-nitro-aniline in di-chloro-methane leads to the title compound, [Co(III)(C44H28N4)(C6H6N2O2)2]Cl·CH2Cl2. The Co(III) ion lies on an inversion centre and is octa-hedrally coordinated by two N atoms of the NH2 groups of the two 4-nitro-aniline trans-axial ligands and four pyrrole N atoms...

The title salt, [K(C(18)H(36)N(2)O(6))][Co(C(2)H(4))(4)], is one of only two known homoleptic ethyl-enemetalates. The cation and anion are well separated, which gives an unperturbed tetra-hedral anion as is expected for a formally Co(-I)d(10) metal center. The considerable elongation of the C=C bonds of the ethyl-ene ligands [average 1.401 (6) Å], relative to that of free ethyl-ene (1.333 Å), i...
