Crystal structure of bis(l-arginine)copper(II) hexachlorodimercurate, [Cu(l-Arg)2]Hg2Cl6

Copper(II) Supramolecular Complex: Synthesis, Crystal Structure, and Electrochemical Property

“…The copper ion is hexacoordinated and its arrangement may be best described as a distorted octahedral 18. The average bond length of Cu–N is 1.975 Å, which is similar to the values observed in [Cu( l ‐Arg) 2 ]Hg 2 Cl 6 (Arg = Arginine) 19. The medial distance of Cu–O amounts 2.548 Å, which is a little longer than the average value.…”

Crystal structure, Hirshfeld surface analysis and physicochemical characterization of bis[4-(dimethylamino)pyridinium] di-μ-chlorido-bis[dichloridomercurate(II)]

“…Each anion appears to be a distorted edge-shared bitetrahedron, similar to that reported by Larock et al (1987), with its center of mass coincident with a crystallographic center of symmetry. The two independent HgÁ Á ÁCl bridging distances are 2.539 (2) and 2.542 (2) Å , leading to a slightly asymmetric bridging system as has been found in most structures containing the [Hg 2 Cl 6 ] 2À moiety (Linden et al, 1999;Zabel et al, 2008). In each anion, the two terminal Hg-Cl bonds are quite short [Hg1-Cl1 = 2.371 (2) and Hg1-Cl3 = 2.380 (2) Å , Hg2-Cl4 = 2.367 3and Hg2-Cl5 = 2.392 (2) Å ] with a Cl1-Hg1-Cl2 and Cl4-Hg2-Cl6 angles of 112.01 (9) and 112.72 (10) , respectively.…”

Metal–organic framework in anl-arginine copper(ii) ion polymer: structure, properties, theoretical studies and microbiological activity

“…There are monomeric as well as two one-dimensional coordination polymers consist of metals ions, including [Co(L-Arg) 2 (NO 2 ) 2 ]$NO 3 $2H 2 O, [Cu-(L-Arg) 2 ]Hg 2 Cl 6 and {[Cu 2 (L-Arg) 2 (2,2 0 -bpy)(m 2 -ClO 4 ) 2 ]$2ClO 4 $ 4H 2 O} n . [14][15][16] Therefore, in the present paper, we describe in details the crystal structure of a novel one-dimensional copper(II) coordination polymer with a formula of {[Cu(L-Arg) 2 (m-4,4 0 -bpy)]-Cl 2 $3H 2 O} N (1). The polymer framework was produced with bridged-organic ligand as 4,4 0 -bipyridine.…”
