Lr. Macgillivray et Jl. Atwood, SYNTHESIS AND STRUCTURE OF (H2O)(12-CROWN-4)-CO(II)(CO(II)CL-3)(MU-CL) ISOLATED FROM A LIQUID CLATHRATE MEDIUM, Journal of chemical crystallography, 27(8), 1997, pp. 453-456
The crystal structure of (H2O)(12-crown-4)Co(II)(Co(II)Cl-3)(mu-Cl) 1
is reported. Crystal data for 1: monoclinic, space group P2(1)/m, a =
7.958(8) Angstrom, b = 12.006(1) Angstrom, c = 69.017(9) Angstrom, bet
a = 107.896(2)degrees, D-c = 1.84 g cm(-3), Z = 2, R1 = 0.025, wR2 = 0
.059, The crown ether acts as a tetradentate ligand and partially comp
letes the binding sphere of the Co(II) ion which also includes one wat
er oxygen atom and a bridging chloride ligand, the latter of which may
be regarded to originate from a [CoCl4](2-) ion.
