Crosses or chains? The two free pyridyl groups of a dimeric, triethanolamine‐triisonicotinate‐bridged palladium complex allow the formation of a unique microcross morphology or chain array of microcrystals (see picture), depending on the reaction conditions. These morphologies arise from interactions between microcrystals involving hydrogen bonding of the free pyridyl groups on the microcrystal surface and water molecules.
