Fig. 2: Crystal structure of Ni-tPBA3.
From: Identifying and tuning coordinated water molecules for efficient electrocatalytic water oxidation
a The crystallography asymmetric unit of Ni-tPBA3, with five kinds of nickel center and the corresponding coordination environment. b Staggered coordination 2D layer structure constructed by tPBA in Ni-tPBA3. c 1D chain constructed under BTC-assisted extension in Ni-tPBA3. The illustration are Cartesian coordinates, with the a, b, and c axes marked in red, green, and blue. d The sra topology (zeolite ABW) with 4-connect net of Ni-tPBA3. e Mortise and tenon structure in Ni-tPBA3 (The pink triangle represents the supramolecular stacking mode).
