catena-Poly[[(liriodenine-κ2 N,O)lead(II)]-di-μ-chlorido]

Abstract

The title compound, [PbCl2(C17H9NO3)]n, was synthesized by the hydro­thermal reaction of PbCl2 and liriodenine. The lead(II) atom has a distorted octa­hedral environment made up of the O and N atoms of the liriodenine ligand [Pb—O 2.666 (4) Å, Pb—N 2.587 (5) Å, O—Pb—N 61.78 (14)°] and four bridging chloro ligands, which link the complex mol­ecules into infinite chains along the a axis. Both crystallographically independent chloro-bridges are asymmetric, so that the Pb atom participates in two short [2.6872 (18) and 2.7952 (18) Å] and two noticeably longer Pb—Cl bonds [2.9626 (18) and 3.031 (2) Å].

Comment

Liriodenine, 8H-[1,3]benzodioxolo[6,5,4-de]benzo[g]quinolin-8-one, is an oxo-aporphine alkaloid, which was isolated from the Z. nitidum (TCM) spiders found in China (Chen et al., 2009). With its N and carbonyl O donor atoms, liriodenine can serve as bidentate chelate ligand in metal complex. In our previous work, the synthesis, crystal structures and anticancer activity of platinum(II) and ruthenium(II) complexes of liriodenine were reported (Chen et al., 2009). In order to extend our knowledge on liriodenine coordination chemistry we turned to the main-group metals and report herein the the first structure of lead(II) complex with liriodenine.

As shown in Fig.1, similarly to what was observed in the structure of catena-[cis-bis(µ2-chloro)-(3-methylpyridine-N)]lead(II) (Engelhardt et al., 1987), the Pb1 atom in the title compound is six-coordinated by the O1 and N1 atoms of the liriodenine ligand [Pb1—O1 2.666 (4) Å, Pb1—N1 2.587 (5) Å] and four µ2-chloro-atoms which link the complex molecules into infinite chains running along the a axis. The chloro-bridges show noticeable asymmetry with the Pb1—Cl1 [2.7952 (18) Å] and Pb1—Cl2 [2.6872 (18) Å] bonds being significantly shorter than Pb1—Cl1ii [3.031 (2) Å], and Pb1—Cl2i [2.9626 (18) Å] (see Fig. 1). The octahedral coordination of the Pb1 atom shows considerable distortion due to the presence of the chelate ligand [angle O1—Pb1—N1 is equal to 61.78 (14)°] and the asymmetry of the chloro-bridges, e.g. the N1—Pb1—Cl2 and O1—Pb1—Cl2 angles are 84.80 (11)° and 136.98 (11)°, respectively. The overall geometry of the complex compares quite well with that of catena-(cis-bis((µ2-chloro)-(3-methylpyridine-N)) lead(II) (Engelhardt et al. 1987), and the geometric parameters of liriodenine are close to those reported previously (Chen et al., 2009).

Experimental

PbCl2 (0.8 mmol, 0.222 g) and liriodenine (0.8 mmol, 0.220 g) were thoroughly mixed in a mortar with a pestle, and placed in a thick-walled Pyrex tube (ca 20 cm long). After addition of EtOH (0.6 ml) and H2O (0.3 ml), the tube was frozen with liquid nitrogen, evacuated under vacuum and sealed with a torch. The tube was heated at 110°C for 2 days and then slowly cooled down to room temperature; brown-red block crystals were obtained. Yield: 40%.

Refinement

The H atoms bonded to C atoms were positioned geometrically (C—H 0.93 Å for aromatic and 0.97 Å for aliphatic qroups). and included in the refinement in riding model approximation with Uiso(H) = 1.2Ueq(C). The highest peak of 1.19 e Å-3 is located at 1.65 Å from O3; the deepest hole of -1.28 is found at a distance of 0.94 Å from Pb1.

Special details

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.
