To a solution of [Mn(bpb)Cl(H2O)] (0.425 g, 1 mmol) in 20 ml of methanol was added a solution of NaN3 (0.065 g, 1 mmol) in a minimum volume of H2O. After stirring for 30 min at room temperature, the dark brown solution was filtered and allowed to stand for about one month at room temperature to form dark brown crystals of 1, [Mn(bpb)(N3)(CH3OH)]. The crystals were collected by suction filtration, washed with a minimum amount of water, and dried in vacuo. Elemental analysis: C19H16MnN7O2, Calcd: C 51.25%, H 3.62%, N 22.02%, Found: C 51.68%, H 3.87%, N 22.35%.. IR (KBr): 2035 cm-1 (N3-), 1622 cm-1 (C=O).
The H atom bonded to the O atom was located in a difference map and refined isotropically with a distance restraints of O—H = 0.84 (2) Å. Other H atoms were positioned geometrically and refined using a riding model (including
about the ethanol C—C bond), with C—H = 0.93–0.96 Å and with Uiso(H) = 1.2 (1.5 for methyl group) times Ueq(C).The planar tetradentate ligand bpb2-, bpb = 1,2-bis(pyridine-2-carboxamido)benzene, can coordinate four equatorial sites of six-coordinated paramagnetic cations, leaving two free axial positions to be occupied by bridging ligands. It is hence, one of the ideal candidates to act as a co-ligand for constructing expanded structures (Colacio et al., 2005; Ni, Kou, Zheng et al., 2005; Ni, Kou, Zhang et al., 2005; Ni, Kou, Zhao et al., 2005; Dominguez-Vera et al., 2005; Havranek et al., 1999; Lin et al., 2003; Liang et al., 2007; Zhang et al., 2006). Mn(III) compounds, with a high-spin ground state related to the Mn(III) ion (S = 2) and an apparent magnetic anisotropy of hexacoordinated Mn(III) centres due to Jahn—Teller distortion, usually display appealing magnetic properties (Lecren et al., 2007).
We originally attempted to synthesize complexes featuring azido-bridged Mn(III) metal chains by reaction of the [Mn(III)(bpb)]2- building blocks with NaN3. But, we fortuitously obtained title compound (I), and we report herein its crystal structure.

The planar tetradentate ligand bpb2-, bpb = 1,2-bis(pyridine-2-carboxamido)benzene, can coordinate four equatorial sites of six-coordinated paramagnetic cations, leaving two free axial positions to be occupied by bridging ligands. It is hence, one of the ideal candidates to act as a co-ligand for constructing expanded structures (Colacio et al., 2005; Ni, Kou, Zheng et al., 2005; Ni, Kou, Zhang et al., 2005; Ni, Kou, Zhao et al., 2005; Dominguez-Vera et al., 2005; Havranek et al., 1999; Lin et al., 2003; Liang et al., 2007; Zhang et al., 2006). Mn(III) compounds, with a high-spin ground state related to the Mn(III) ion (S = 2) and an apparent magnetic anisotropy of hexacoordinated Mn(III) centres due to Jahn—Teller distortion, usually display appealing magnetic properties (Lecren et al., 2007).
We originally attempted to synthesize complexes featuring azido-bridged Mn(III) metal chains by reaction of the [Mn(III)(bpb)]2- building blocks with NaN3. But, we fortuitously obtained title compound (I), and we report herein its crystal structure.
