The cover picture shows how a novel tetranuclear Ni II complex [Ni 4 L 4 1 (μ‐tp‐κ 4 ‐O)(H 2 O) 2 (μ‐tp‐κ 2 ‐O)]·2C 2 H 5 OH·CH 3 OH·3H 2 O [L 1 = N‐(3‐aminopropyl)‐5‐bromosalicylaldimine] acts as an active catalyst for the partial oxidation of cyclohexene into its epoxide product when it is immobilized over a network of hexagonal mesoporous silica. Herein the catalytic sites allow the formation of epoxide over their surfaces. tert ‐Butyl hydroperoxide acts as an oxidant for the partial oxidation process. A dinuclear unit is formed, in which the Ni II is bridged by a phenolato group, and two such units are connected through a terephthalate moiety to form a tetranuclear nickel(II) complex. The tetranuclear units are connected to each other by another terephthalate moiety in its bis(monodentate) mode to form one‐dimensional networks. Details are described in the article by P. Banerjee et al. on p. 5033 ff. The artwork was designed by Mr. Jishnunil Chakraborty and Mr. Gopal Das.
