The first compound with an unusual type of anion, [Li(SR)2]–: bis(μ2-aqua-d2)tetrakis(aqua-d2)dilithium(I) bis[bis(tri-tert-butoxysilanethiolato-κ2O,S)lithate(I)] dihydrate-d2
摘要:
The title complex, [Li-2( D2O)(6)][Li(C9H27SSiO3)(2)](2) center dot 2D(2)O, is the rst compound with an S - M bond ( M = alkali metal) within an unusual type of lithate anion, [ Li( SR)(2)]. {where R is Si[OC(CH3)(3)](3)}. There is a centre of symmetry located in the middle of the Li2O2 ring of the cation. All Li atoms are fourcoordinate, with LiO4 ( cations) and LiO2S2 ( anions) cores. The singly charged [ Li(SR)(2)]. anions are well separated from the doubly charged [ Li-2(D2O)(6)](2+) cations; the distance between Li atoms from differently charged ions is greater than 5 A. Both ion types are held within an extended network of O - D center dot center dot center dot O and O - D center dot center dot center dot S hydrogen bonds.
