In the title compound, [Ho(NO3)3(C12H16N3O2)2], the HoIII ion is ten-coordinated in a distorted bicapped square-anti­prismatic environment by two N,O-bidentate nitronyl nitroxide radical ligands and three O,O′-bidentate nitrate anions. Complex mol­ecules are connected by C—H⋯O hydrogen bonds into a three-dimensional network.

Comment top

As a continuation of our work on the complexes adopting nitroxide radicals as the ligand, the title new Ho complex is reported. In this compound, the metal ion is ten-coordinated by two radicals and three nitrate anions (Fig. 1). The radical behaves as a bidentate chelating ligand through one oxygen of nitronyl nitroxide and one nitrogen of pyridyl, while the other oxygen of nitronyl nitroxide remains uncoordinated. The coordination sphere of the Ho atom is completed by the η2-coordination of three NO3- anions. The complexes are further connected by C—H···O hydrogen bonds (Table 1) into a three-dimensional framework, as shown in Fig. 2.

Experimental top

The compound was synthesized by the following procedure. Ho(NO3)3.6H2O (0.046 g, 0.2 mmol) and NIT2Py (0.047 g, 0.2 mmol) were dissolved in 10ml of anhydrous THF. The mixture was stirred at room temperature for four hours and then filtered. The dark brown filtrate was allowed to stand in the dark for one week. Dark brown crystals were obtained.

Refinement top

H atoms were positioned geometrically (C—H = 0.93–0.96 Å) and refined using a riding model, with Uiso(H) = 1.2Ueq(C) and 1.5Ueq(Cmethyl).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
