Bis(2-hydroxyethanaminium) tetrachloridopalladate(II)

Abstract

In the title compound, (C2H8NO)2[PdCl4], 2-hy­droxy­ethanaminium cations and tetra­chloridopalladate(II) dianions crystallize in a 2:1 ratio with the anion residing on a crystallographic inversion center. The cations and anions are linked in a complex three-dimensional framework by three types of strong hydrogen bonds (N—H⋯O, N—H⋯Cl, and O—H⋯Cl), which form various ring and chain patterns of up to the ternary graph-set level.

“…,DUWQES (Zheng et al, 2010), LAMYUV(Zeng et al, 2012), TIVWOM(Wang et al, 2014b), TOBDUK(Hang & Ye, 2008)] and bridging [COHFOW(Ren et al, 2013), DEZHIB(Zeng, 2013), GADVEP(Li et al, 2016), TIVXAZ(Wang et al, 2014b)] coordination modes. BTA also can show catenatype structures [DEZHOH(Zeng, 2013), DUWQAO (Zheng et al, 2010), DUWQIW (Zheng et al, 2010), GUTZAX (Wang et al, 2009), IPAGIQ (Wang et al, 2011), TIVXED (Wang et al, 2014b), TIVXON (Wang et al, 2014b), UFETEF (Hu et al, 2008), YATPAM (Liu, 2012), ZIPLOB (Chen et al, 2010) etc].In most cases, MEA behaves as a chelating ligand; however, there are metal complexes in which non-coordinating MEA molecules are situated in the outer coordination sphere [AXUQAN(Ibragimov et al, 2016c), FAFTOV(Spitsin et al, 1986), TIRQEQ(Halvorson et al, 1995), WUZZOH(Guzei et al, 2010b) etc]. Mixed-ligand metal complexes including BTA and MEA have not been reported in the CSD up to date.…”
