(M3L4 + M2L4): a unique example of a co-crystal containing M3L4 and M2L4 metallocages

Recent Developments in the Preparation and Chemistry of Metallacycles and Metallacages via Coordination

“…A study of cages formed from Pd(II) ions and 1,3bis(imidazol-1-ylmethyl)-2,4,6-trimethylbenzene by Wang and Lio revealed conditions to isolate M 3 L 4 , M 2 L 4, or the cocrystallization of both species. 278 The M 3 L 4 species contains a central Pd(II) site from which two four ligands form the basis of two fused metallacycles. The M 2 L 4 cage is simpler in design, sharing structural characteristics of many M 2 L 4 species wherein homoleptic coordination at each Pd(II) center is observed.…”

Tailoring the dimensionality of metal complexes via ligand modifications

“…The ligands used, denoted as L1, L2, L3 and L4 are outlined in Scheme (I) [1,3-bis(imidazol-1-ylmethyl)benzene (L1), 1,3-bis(imidazol-1-ylmethyl)-5-methylbenzene (L2), 1,3bis(imidazol-1-ylmethyl)-2,4,6-trimethylbenzene (L3), 1,3bis(2-methylimidazol-1-ylmethyl)-2,4,6-trimethylbenzene (L4)]. L1, L2 and L3 have previously been employed by our group and other researchers in the formation of metal complexes involving various 3d-block metal ions, such as Cd II , Cu II , Zn II , Ag II , Ni II and Co II (Arhangelskis et al, 2021;Liu et al, 2021;Alen et al, 2015;Bisht et al, 2014a,b;Dobrzan ´ska et al, 2006;Zhang et al, 2014;Ma et al, 2013;Dobrzan ´ska, 2011;Strasser et al, 2010;Liu et al, 2009;Mukherjee et al, 2008;Liu, Hu et al, 2001;Liu, Su et al, 2001;Sun et al, 2000;Yang et al, 2013;Yao et al, 2008;Sui et al, 2005Sui et al, , 2001Ma et al, 2003;Fan et al, 2001). On the other hand, L4 is novel and used for the first time in this study.…”
