(Cryptand-222)potassium(+) (hydrogensulfido)[5,10,15,20-tetrakis(2-pivalamidophenyl)porphyrinato]ferrate(II)
As part of a systematic investigation for a number of Fe(II) porphyrin complexes used as biomimetic models for cytochrome P450, crystals of the title compound, [K(C(18)H(36)N(2)O(6))][Fe(II)(C(64)H(64)N(8)O(4))(HS)], were prepared. The compound exhibits a non-planar conformation with major ruffling and saddling distortions. The average equatorial iron-pyrrole N atom [Fe-N(p) = 2.102 (2) Å] bond...
متن کامل(2.2.2-Cryptand)potassium tetracarbonylcobaltate(−I)
The title salt, [K(C18H36N2O6)][Co(CO)4], is an example of a classical carbonyl-metalate. The asymmetric unit contains one cation and one tetrahedral anion, both in general positions. Based on comparison of the four carbonyl C-O bond lengths and C-Co-C angles, the anion is unperturbed by the cation, which is normal for an alkali metal fully encased by a cryptand cage.
متن کاملCRYSTAL STRUCTURE OF SODIUM-POTASSIUM .ANTIMONIDE (NaiKSb)
X-ray analysis of Na2KSb a photoemissive material discovered by Sommer has led to the determination of its crystal structure. The unit cell is described by the space group Fm3m-01l5 with four antimony atoms at (0,0,0; O,t,!; t,O,t; t,t,O) + 0,0,0; four potassium atoms at ( ) + t,t,! and eight sodium atoms at ( ) + t,t,t and t,t,t. The crystal structure of Na2KSb has a great resemblance to that ...
متن کاملSpectroscopic Study of the Interaction Between TCNQ and Cryptand 222 in Chloroform Solution
The interaction between 4, 7, 13, 16, 21, 24 - hexaoxa-1,10 - diazabicyclo [8.8.8] hexacosane (C222) and 7,7,8,8- teracyanoquinodimethane (TCNQ) has been studied in chloroform at 25°C. The results indicate a two step mechanism. At the first step, two adducts (assign as P1 and P2) are formed through equilibrium reactions. In continue and through nonequilibrium reactions the adducts are conve...
متن کامل(2.2.2-Cryptand)potassium tetrakis(η2-ethylene)cobaltate(−I)
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...
