The title compound [Nd(L)(NO{sub 3}){sub 3}]2CH{sub 3}CN was formed by reaction of neodymium nitrate with N,N{prime}-bis(4-methoxyphenyl)tetraglycollic diamide (L). The complex crystallizes in the monoclinic system, space group Cc with Z = 4, a = 21.305(6), b = 11.470(4), c = 14.436(3) {angstrom}, {beta} = 97.41(2), V = 3498(2) {angstrom}{sup 3}. The pentadentate organic ligand wraps around the neodymium ion which is also bonded to three bidentate nitrate groups, achieving uncommon undecacoordination with the following mean bond lengths: Nd-O(etheric), 2.703; Nd-O(carbonyl), 2.518; Nd-O(nitrate), 2.546 {angstrom}. 18 refs., 2 figs., 3 tabs.
