Crystal structure of Cs2(B9C2H11)Co(B8C2H10)Co(B9C2H11).H2O, a salt of a three-icosahedral-fragment metallocarborane

Abstract

Tho crystals were found to ba monoclinic with unit cell dimensions, measure.'<! at room temperature (-22), ..!!_ = 7.089 0.004 A., :E.= 19.240 0.014 L, .. = 20.682 0.004 f..., ~ = 98.00 0.06 degrees.There are four forrr.ulaunits, Cs 2 Co 2 B 26 c 6 oH 34 , per unit cell.The density is calculated to be p = 1.87 g/cc. No density measurement was made because the sample was lost.The observed extinction rules, ~, ~ = ~ and .Q!Q., = ~~ correspond to space group P2 1 /c .All atoms lie on the general symmetry related positions, (x;Y2! and x,~'-Y,~'+z).----~~--' .. ,.
