The geometry around this pentacoordinated Zn atom is distorted square pyramid. The Zn(1)AO(1) bond distance (1.972(4) Å and Zn(1)-O(3) bond distance (1.977(4) Å are slightly shorter than that of Zn(2)-O(5) (1.988(4))  and obviously shorter than that of Zn(2)-O(2) (2.152(4) Å and Zn(2)-O(4)ii (2.151(4) Å. The Zn(2)AN(1) bond distance (2.023(4)) and Zn(2)AN(2)ii bond distance (2.019(4) Å are slightly shorter than that ZnAN bond distances reported in the literature , and significantly shorter than other ZnAN bond distances (2.148(3) and 2.156(3) Å reported in the literature . In each ligand PIDC, the imidazole ring and pyridyl ring are almost vertical with a dihedral angle of 76.6¡ã. It is worth noting that the PIDC in 1 adopts a new ¦Ì4-kN, O:kN¡¯, O¡¯:kO¡¯¡¯, 0¡¯¡¯¡¯:kN¡¯¡¯¡¯coordination mode (Scheme 1) to bridge four Zn(II) atoms in bis-N,O-chelating, O,O¡¯-chelating, and monodentate fashions. The overall structure of 1 is a two-dimensional framework, as illustrated in Fig. 2. Moreover, the hydrogen bond (Table 4) occurring at O5--H5A. . .O3i and O5--H5B. . .O1ii give rise to a three-dimensional framework.
