Tris(1,10-phenanthroline)potassium tetraphenylborate, [K(C12H8N2)3][B(C6H5)4]

Bis(1,10-phenanthroline)(2,2,6,6-tetramethylheptane-3,5-dionato)potassium(I) benzene sesquisolvate

“…2). No intramolecular stacking interaction similar to that found in [K 2 (phen) 6 ] 2+ [BPh 4 ] -2 (Bombieri et al, 1984) occurs in the title crystal structure. The distance between parallel planes of phen-ligands (3.48 (5) Å) is typical for stacking distances in related compounds like Ba(dpm) 2 (phen) 2 (Soboleva et al, 1995) or La(dpm) 3 (phen) (Minacheva et al, 2003) or La(hfa) 3 (phen) 2 (Rogachev et al, 2005).…”

“…The K•••O1 and K•••O2 distances are similar because of electron density delocalization in the chelating part of the dpm --anion. The K + ion is displaced from the planes of the phenanthroline ligangs by 0.80 1 (Bombieri et al, 1984).…”

One-dimensional coordination polymers in the crystal structures of sodium and potassium acetylacetonates

“…4) is formed by four O-atoms of two chelating acac -anions (µ 2 -O1, µ 3 -O2 and µ 3 -O3, µ 2 -O4), a chelating phen ligand (N1 and N2) and a bridging water (µ 2 -O1w iii ). The average K-N phen distance (2.868 Å) is close to that observed for hexacoordinated (2.871 Å in K(thd)(phen) 2 [31]) and heptacoordinated (2.834 Å in K 2 (Piv) 2 (phen)(H 2 O) [32]) potassium atoms and is in good agreement with typical values of K-N phen distances in other known potassium complexes with phen [33].…”

Palladium Complexes with the SC6F4H‐4 Ligand – Synthesis, Spectroscopy, and Structures

“…The Pd-S bond lengths of the bridging thiolate ligand are longer than the peripheral ones (Table 3). [22] Structurally characterised dications of the formula [(phen) 2 -K(μ-phen) 2 K(phen) 2 ] 2+ have been reported in [K 2 (phen) 6 ]-(BPh 4 ) 2 , (space group P1) [35] [K 2 (phen) 6 ][Cr 2 (CO) 10 (μ-H)] 2 , (P1) [36] and [K 2 (phen) 6 ][Cu(NPh 2 ) 2 ] 2 (NPh 2 = diphenylamide; P2 1 /n), [37] and the bonding parameters around the eight-coordinate K + ions are very similar in the [a] Radiation wavelength λ = 0.71073 Å; T = 293(2) K; refinement method: full-matrix least-squares on F 2 . Only the crystal structure of [{(C 6 F 5 )Ph 2 P}(C 6 F 5 S)Pd(μ-SC 6 F 5 ) 2 Pd(C 6 F 5 S)-{PPh 2 (C 6 F 5 )}], which also contains both peripheral and bridging SC 6 F 5 units, has been reported.…”
