1 Source of material

The title complex Sm(C12H8N2)2(N3)2(NO3) was synthesized by means of the hydrothermal method. the mixture of Sm(NO3)3.6H2O (0.15 g), phen (C12H8N2, 0.09 g), NaN3 (0.07 g), ethylene glycol (2 mL) and H2O (3.0 mL) was placed into 50 mL Teflon-lined stainless steel vessels and kept at 150 °C for 130 h. The yellow block crystals were isolated with the yield of ca. 77 % [based on Sm(NO3)3·6H2O].

2 Experimental details

H atoms were positioned geometrically and refined by means of a riding model, with C–H = 0.93 Å, with Uiso(H) = 1.2 times Ueq(C). The restraint of delu was employed to deal with the slightly disordered nitrate anion [3].

3 Comment

The rational design and synthesis of coordination compounds using various azide/nitrate/sulfate/carbonate anions and containing–N/O ligands have received extensive attention [3, 4]. The organic ligands and acid radical ions not only can act as bridging units, but also can serve as chelating groups [5, 6], which are favorable for the formation of different dimensional complexes with new structural features. Using three kinds of ligands of 1,10-phenanthroline (phen), azide anion and nitrate anion, we prepared a new 1–D coordination compound Sm(C12H8N2)2(N3)2(NO3) based on Sm3+ cation. Its molecular structural unit (Figure) contains two phen ligands, two N3− anions and one NO3− anion. Each Sm(III) ion adopts nine-coordinated by two O atoms from bidentate NO3− anion and seven N atoms from surrounding two phen ligands and three N3− anions, leading to a tricapped trigonal prismatic coordination geometry {SmN7O2}. The distances of Sm–O and Sm–N bonds are in the range of 2.389(6)–2.623(5) Å and 2.490(7)–2.531(8) Å, respectively. The angles of N–Sm–N and N–Sm–O are in the ranges of 62.74(16)–149.71(17)° and 67.6(2)–140.7(3)°, respectively. The bond lengths and angles are compared with those of previously reported complexes [7, 8]. The adjacent molecular structural units are connected by two μ2–N atoms (N1 and N3) at both ends of the azide ion, extending into a 1–D chain structure along the a axis (DSm(III) … Sm(III) = 6.748 Å). Two coordinated modes of azide anion were observed in the 1–D structure: the azide anion that is built by the N1/N2/N3 contributed two N atoms (N1 and N3) to coordinate with Sm3+, while the other one built by the N4/N5/N6 only provided one N atom (N4) to be connected with Sm3+, which can be observed in related known complexes [9]. Moreover, there are the weak π–π stacking interactions between parallel phen ligands (C1–C12/N7/N8) in the packing structure.
