Bis(diisopropyl(1,2-bis(diethylcarbamoyl)ethyl)phosphonate)erbium(III) nitrate monohydrate, Er(NO/sub 3/)/sub 3/(i-C/sub 3/H/sub 7/O)/sub 2/P(O)CH-(C(O)N(C/sub 2/H/sub 5/)/sub 2/)(CH/sub 2/C(O)N(C/sub 2/H/sub 5/)/sub 2/))/sub 2/.H/sub 2/O, has been prepared from the trifunctional phosphate ligand and Er(NO/sub 3/)/sub 3/.6H/sub 2/O in ethanol. The complex has been characterized by infrared and NMR spectroscopy and single-crystal X-ray diffraction analysis. The complex was found to crystallize in the monoclinic space group P2/sub 1//n with a = 13.438 (2) A, b = 22.022 (4) A, c = 19.596 (5) A, ..beta.. = 106.21 (2)/sup 0/, Z = 4, V = 5568 (2) A/sup 3/, and rho/sub calcd/ = 1.38 g cm/sup -3/. The structure was solved by heavy-atom techniques. The structure contains an Er(III) ion bonded to the oxygen atom of a water molecule, oxygen atoms of three bidentate nitrate ions, and the phosphoryl oxygen atoms of two of the potentially tripodal ligand (i-C/sub 3/H/sub 7/O)/sub 2/P(O)CH(C(O)N(C/sub 2/H/sub 5/)/sub 2/)(CH/sub 2/C(O)N(C/sub 2/H/sub 5/)/sub 2/). The overall erbium ion coordination number is 9. Two of the four carbonyl oxygen atoms are hydrogen bonded with the coordinated water molecule, while the remaining two carbonyl oxygen atoms, remain uncoordinated. 12 references, 1 figure, 2 tables.
