A new bimetallic MOF (BMOF) has been synthesized using iron and zinc as inorganic metal nodes and 1,4-benzenedicarboxylic acid (BDC) as the organic linker molecule. BMOF was confirmed by single-crystal X-ray diffraction (SCXRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy high-angle annular dark-field imaging (TEM-HAADF), field emission scanning electron microscopy energy-dispersive X-ray analysis (FESEM-EDX), vibrating sample magnetometry (VSM) and inductively coupled plasma mass spectrometry (ICP-MS) analysis. The synthesized BMOF shows excellent optical and magnetic properties. BMOF acts as a heterogeneous catalyst and shows high catalytic activity towards bis(indolyl)methane synthesis and photocatalytic degradation of methylene blue (MB) under visible-light illumination.

An environmentally benign, step economical synthesis of ketones directly from aldehydes has been developed using hypervalent iodine as an oxidant. The key features of this protocol are its mild conditions without the use of any heavy and toxic metals for the synthesis of a wide range of ketones.
