A REDETERMINATION OF THE STRUCTURE OF DIETHYLENETRIAMINETRIOXOMOLYBDENUM(VI)

[Mo(C4H13N3)O3], M(r) = 247.11, orthorhombic, Pbcm, a = 6.890 (1), b = 10.248 (2), c = 11.691 (2) angstrom, V = 825.5 (3) angstrom3, Z = 4, D(m) = 1.99 (1), D(x) = 1.99 g cm-3, lambda(Mo K-alpha) = 0.71069 angstrom, mu = 15.19 cm-1, T = 295 K, F(000) = 496, R = 0.026, wR = 0.031 for 2203 observed unique reflections with I > 3-sigma(I). The Mo atom has a distorted octahedral coordination geometry and it is bonded strongly to three O atoms [mean Mo-O = 1.75 (1) angstrom], but only weakly to the diethylenetriamine N atoms [mean Mo-N = 2.32 (1) angstrom]. The structure consists of [Mo(C4H13N3)O3] units linked by hydrogen bonds of type N-H...O.
