Abstract

Key indicators: single-crystal X-ray study; T = 293 K; mean (C-C) = 0.006 Å; R factor = 0.037; wR factor = 0.101; data-to-parameter ratio = 11.2. ExperimentalCrystal data [Rb(C 6

“…The planes of the carboxylic/carboxylate groups (O1/C1/C2/O2) and (O3/C6/C5/O4) form dihedral angles with the ring (C2/C3/C4/C5/N1/N2) plane of 75.87 (16) and 6.65 (21), respectively. The Rb-O distances are in the range from 2.987 (3) Å to 3.137 (3) Å, which are well within the range reported in the literature for other rubidium complexes (Yang et al 2008;Cametti et al, 2005;Wiesbrock & Schmidbaur, 2003;Shannon, 1976;Devi & Vidyasagar, 2000). Rb-N bond lengths also lie within the normal ranges found for similar bonds in the literature (Yang et al 2008).…”

“…A variety of metal-pyrazine-2,3-dicarboxylic acid complexes have been characterized, including the calcium (Ptasiewicz-Bak & Leciejewicz, 1997a;Starosta & Leciejewicz, 2005), magnesium (Ptasiewicz-Bak & Leciejewicz, 1997b), sodium (Tombul et al, 2006), caesium (Tombul et al, 2007), potassium (Tombul et al, 2008a) and lithium (Tombul et al, 2008b) complexes. For Rb-N bond lengths, see: Yang et al (2008); Cametti et al (2005); Wiesbrock & Schmidbaur (2003); Shannon (1976); Devi & Vidyasagar (2000).…”

Crystal structure of caesium(I) hydrogen maleate, Cs(C4H3O4)

“…The anion is linked to two caesium cations, while the Cs + cation is surrounded by seven organic ligands, three of which are coordinated by employing both Oatoms and the other four are coordinated solely by Oatoms. The Cs-Odistances are in the range from 3.196 (2) to 3.466 (2) Å,which are well within the range reported in the literature for other caesium complexes [10][11][12]. In the crystal structure, intramolecular hydrogen bonds occur, linking carboxylate Oatoms.…”

Effects of the Alkali-Metal Cation Size on Molecular and Extended Structures: Formation of Coordination Polymers and Hybrid Materials in the Homologous Series [(4-Et-C6H4OM)·(diox)n], M = Li, Na, K, Rb, Cs

“…There have also been several homologous nitro-functionalized aryloxide series reported. − Nonaryloxide examples of homologous alkali-metal complexes have been characterized, for example, the hexamethyldisilazide − and tert -butoxide , series.…”
