Crystal structure of tris[(4,7,13,16,21,24-hexaoxa-1,10-diazabicyclo[8.8.8]hexacosane-κ8N2,O6)rubidium] rubidium nonastannide

Crystal structure of rubidium methyl­diazo­tate

The title compound, Rb+·H3CN2O-, has been crystallized in liquid ammonia as a reaction product of the reductive ammonolysis of the natural compound streptozocin. Elemental rubidium was used as reduction agent as it is soluble in liquid ammonia, forming a blue solution. Reductive bond cleavage in biogenic materials under kinetically controlled conditions offers a new approach to gain access to s...

Crystal structure of rubidium peroxide ammonia disolvate

The title compound, Rb2O2·2NH3, has been obtained as a reaction product of rubidium metal dissolved in liquid ammonia and glucuronic acid. As a result of the low-temperature crystallization, a disolvate was formed. To our knowledge, only one other solvate of an alkali metal peroxide is known: Na2O2·8H2O has been reported by Grehl et al. [Acta Cryst. (1995), C51, 1038-1040]. We determined the pe...

Crystal structure of tris[(4,7,13,16,21,24-hexa­oxa-1,10-di­aza­bicyclo­[8.8.8]hexa­cosane-κ8 N 2,O 6)rubidium] rubidium nona­stannide

The crystal structure of the title compound, [Rb(C18H36N2O6)]3RbSn9, consists of deltahedral [Sn9]4- cluster anions, Rb+ cations and cryptand mol-ecules, which partially sequester the cations. Those cations, which are not coordinated by cryptand mol-ecules, are neighboured directly to the [Sn9]4- clusters and inter-connect them to form ∞1[RbSn9]3- chains. These chains extend parallel to [001] a...

SYNTHESIS AND CRYSTAL STRUCTURE OF [PPh ] [WOS (CUNCS) ]

The reaction of [PPhJ, NOS,] with CuCl and KSCN (1 :3:3) in acetone produces the yell-ow crystals of [PPh,], [WOS,(CuNCS),]. The crystals are triclinic, space group P1(2), z=2, a=12.4823(7), b=12.9224(7), c=18.6395(10)?, ?=83.907(5), ?= 73.152(4), Y= 65.194(4)'. The crystal structure was determined by single crystal Xray diffraction methods (Mo-K ?) and refined by least-squares calculations ...
