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.

The closed ring confining truss is set along the periphery of the reticulated shell, and the stiffening truss is set in the middle single-layer shell which can take advantage of the architectural shape. These measures resolve the contradiction between overall stability and temperature stress, and also avoid the shell thrust act on the lower concrete structure directly. Besides, these measures simplify the design of the shell bearing and the concrete structure, and the cost of the concrete structure can also be saved.
