The zinc(II) compound, [Zn 3 (HL) 6 ] n (1) (H 2 L = 3-hydroxypyridine-2-carboxylic acid) was synthesized by a solvothermal reaction of Zn(NO 3 ) 2 ·6H 2 O and 3-hydroxypyridine-2-carboxylic acid as raw materials. The structure of complex 1 was determined by single-crystal X-ray diffraction analysis and further characterized by elemental analysis, Fourier transform infrared spectroscopy, thermogravimetric analysis, as well as powder X-ray diffraction. X-ray structure analysis demonstrates that the complex crystallizes in the monoclinic system, space group P2

Two new metal‐organic frameworks (MOFs), namely {[Zn2(L)2(4,4′‐bipy)1.5] ⋅ H2O}n (1) and {[Ni(L)(4,4′‐bipy)(H2O)2] ⋅ (H2O)5}n (2), where H2L=4,5‐bis(pyrazol‐1‐yl) phthalic acid, have been solvothermally synthesized and characterized. The single‐crystal X‐ray analyses showed that 1 and 2 present a 3D ths network and a cds network, respectively. The photocatalytic properties for both frameworks showed that they can photodegrade dye methylene blue (MB) and methylene orange (MO) under UV light irradiation. The possible photocatalytic mechanism has been addressed using band gap calculation by taking assistance of density of states (DOS) and partial DOS (pDOS) calculations.
