We report on a novel phosphoramide complex with formula Cu(NO3)(2)([C5H10N](3)PO)(2). This complex is the first example of a copper monomeric phosphoric triamide having an octahedral Cu[O](6) coordination environment. Cu(NO3)(2)([C5R10N](3)PO)(2) crystallizes in the monoclinic space group P2(1)/n with the Cu atom located at an inversion center, as determined by single-crystal X-ray diffraction. Magnetic measurements along the principal crystallographic directions of the single crystal indicate that the complex is a paramagnet with very low magnetic anisotropy. Electron paramagnetic resonance spectra reveal the presence of two Cu2+ sites and make it possible to extract the hyperfine coupling.
