Both crystallographically unique Zn atoms exit as an octahedral geometry. The four equatorial positions of Zn1 atom are occupied by the carboxylate-oxygen atoms of the two tartrates, and the two oxygens of the left four carboxylate-oxygen atoms coordinate to two different Zn2 atoms, respectively, forming infinite coordination polymer chains. The left two of the trans equatorial positions of Zn2 atom are completed with two oxygen atoms of two water molecules. The axial positions of both Zn atoms are occupied by the nitrogen atoms from different 4,4'-bipyridine molecules to give a 2D rectangular-grid layers with a cavity dimension of 0.51165(3)nm×1.13896(5) nm. A three dimensional network is formed by the crystallization water chains joined by the carboxylate-oxygen atoms through hydrogen-bonding interactions.

Though enantioslectivity in the epoxidation of some substrates with soluble polymer-supported tartrates is a little lower than that with solution-phase tartrates, it is higher than enantioslectivity with insoluble polystyrene resin-supported tartrates, linear poly s and corrosslinked poly s. It is obvious that soluble polymer-supported tartrates have good catalytic activity and enantioselectivity.
