ZnII ion is six‐coordinated by two O atoms from two H2BTMIPA2− ligands, by two N atoms from two BIF ligands and by two water molecules, forming a distorted octahedral ZnN2O4 coordination geometry. Adjacent ZnII ions are linked by H2BTMIPA2− ligands and BIF ligands, leading to the formation of a two‐dimensional (2D) (4,4)‐sql network, and intermolecular hydrogen‐bonding interactions connect the 2D layer
