Synthesis and Characterization of Structurally Diverse Alkaline-Earth Salen Compounds for Subterranean Fluid Flow Tracking

“…A search of the structure literature reveals that surprisingly few alkaline-earth salen derivatives have been reported . Of the 22 compounds structurally characterized with at least one alkaline-earth metal coupled to a salen backbone, the majority of the family members are heterometallic species with the alkaline-earth cations located externally to the salen cavity, including: Mg–Cu, − Mg–Ni, Ca–Ni, Ca–U, Ca–Cu, , Sr–Cu, Ba–Cu, , Ba–Ni, , and Ba–Fe . Only six homometallic compounds have been reported: [Be­(μ-(κ 4 -(O,N,N′,O′)­salen))] 2 ·H 2 O, bis­(μ-3,3′-(ethane-1,2-diyl bis­(iminiomethyl ylidene)) bis­(2-oxybenzoate))­diaqua, dimagnesium hexahydrate), aqua,methanol-(ethylendiamine- N , N ′-bis­(2-aldimino-4-methyl-6-formylphenolato)) magnesium, (THF)­(HOEt) 2 Ca­(κ 4 -(O,N,N′O′)­salo-Bu t , (DME)­Ca­(κ 4 -(O,N,N′O′)­saloCy-Bu t ), where saloCy-Bu t = bis­(3,5-di-t-butylsalicylidene)­cyclohexane-1,2-diamine, (HOEt) 3 Sr­(κ 4 -(O,N,N′O′)­salo-Bu t ) .…”
