Bis(2,2′-bi­pyridine)-1κ²N:N′;3κ²N:N′-tris(μ-α-methyl­acryl­ato-1:2κ²O:O′)­tris(μ-α-methyl­acryl­ato-2:3κ²O:O′)(nitrato-2κ²O:O′)­dizinc(II)­praseodymium(III)

The crystal structure of the title heteronuclear complex, [PrZn₂(C₄H₅O₂)₆(NO₃)(C₁₀H₈N₂)₂], is made up of discrete mol­ecules of a trinuclear Zn—Pr—Zn complex with the central Pr atom bridged by three bidentate α-methyl­acryl­ate groups to each of the two Zn atoms. In the complex, the Pr atom is coordinated by six O atoms from the bridging methyl­acryl­ate groups and by two O atoms from a bidentate chelate nitrato group in a distorted square antiprismatic configuration. Each Zn ion is five-coordinated by three O atoms from three bridging methyl­acryl­ate groups and by two N atoms from a bi­pyridine in a distorted trigonal–bipyramidal configuration.

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.
