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.

In ruling out this objection I declare that the philosophers did not postulate the possibility of an infinity in causes essentially ordered, but only in causes accidentally ordered, as is evident from Avicenna\'s Metaphysics, B. VI, chapter five, where he speaks of an infinity of individuals in a species.

为了回应这一反驳，我断言那些哲学家们并没有假定存在无限的本质性因果链的可能，而仅仅是假设了存在无限偶然性因果链的可能，证据就是阿维森纳《形而上学》第十章第五节，在这里他谈及了某一物种个体的无限性。
