Tetraaquabis(μ₂-4,4′-bipyridine)dodecakis(μ₂-2-methylprop-2-enoato)octakis(2-methylprop-2-enoato)tetraytterbium(III)tetrazinc(II)

B. Wu and C. Zhao

The asymmetric unit of the title compound, [Yb₄Zn₄(C₄H₅O₂)₂₀(C₁₀H₈N₂)₂(H₂O)₄], contains half of a centrosymmetric octanuclear molecule in which each Zn^II ion is four-coordinated by three O atoms from three 2-methylprop-2-enoate (L) ligands and one N atom from a 4,4′-bipyridine (bipy) ligand in a distorted pyramidal geometry. The two independent Yb^III ions, each coordinated by eight O atoms in an irregular geometry, exhibit different coordination environments, viz. one water molecule, five bridging bidentate and one chelating bidentate carboxylate groups for one Yb^III ion, and one water molecule, three bridging bidentate and two chelating bidentate carboxylate groups for the other Yb^III ion. In the crystal structure, intermolecular O—H

O and C—H

O hydrogen bonds help to establish the packing.

Comment top

The study of heterometallic complexes containing d-transition metal and lanthanide(III) cations connected by bridging ligands is being actively pursued because of their relevance in solid-state technology and as models for magnetic studies. As a contribution to a structural study of heterometallic complexes containing d-transition metal and rare-earth(III) cations, herewith we report the synthesis and crystal structure of the title compound, (I).

The crystal structure of the title Yb—Zn complex is similar to the known crystal structures of the Gd—Zn and Tb—Zn complexes (Wu et al., 2003, 2004). As shown in Figure 1, the complex consists of a discrete octanuclear molecule, which possesses a symmetry center between the two ytterbium (III) ions. All bridges between the metallic ions are formed by two kinds of ligands. Two Yb^III ions are linked by two carboxylato groups. Zn^II and Yb^III ions are bridged by three carboxylato groups, and two Zn^II ions are linked by 4,4'-bipy molecule. There are two different coordination circumstances for the ytterbium ions in the titled complex. One ytterbium [Yb1] is coordinated by eight O atoms from one water molecule, three bridging bidentate and two chelating bidentate carboxylato groups. The other [Yb2] is also coordinated by eight O atoms, but from five bridging bidentate, one chelating bidentate carboxylato groups and a water molecule. The coordination sphere around each ytterbium (III) ion is irregular. Each zinc(II) ion is four-coordinated by three O atoms from three bridging carboxylato groups and one N atom from 4,4'-bipy group. The coordination polyhedron is a distorted tetrahedron. As is the common case, the carboxylato groups in the title complex serve as chelating or bridging bidentate ligands. The separations of Yb1···Zn1, Zn1···Zn2, Yb2···Zn2 and Yb2···Yb2* (symmetry code: -x, 1 - y, -z) are 3.870 (1), 11.189 (1), 4.012 (1) and 4.745 (1) Å, respectively. In the crystal, O—H···O and C—H···O hydrogen bonds (Table 1) help to establish the packing.

Experimental top

YbL₃ (HL = CH₂C(CH₃)COOH), has been prepared following the known procedure (Lu et al., 1995). YbL₃ (860 mg, 2.0 mmol; HL=CH₂C(Me)CO₂H) and Zn(NO₃)₂.6H2O (240 mg, 0.8 mmol) were dissolved in H₂O (20 ml) and adjusted pH=4.1 with HL (0.1 M). EtOH (3 ml) solution of 4,4'-bipy (60 mg, 0.4 mmol) was added to the mixed solution with stirring. After filtration, the filtrate was allowed to stand at room temperature and single crystals suitable for X-ray work were obtained after 2 weeks.

Special details top

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.
