The first hemidirected nine coordinate lead(II) complex, crystal and molecular structure of [Pb(BzImH) 2 py (H 2 O) 2 (NO 3 ) 2 ] · (BzImH) 2 py · H 2 O, (BzImH) 2 py=2,6-Bis(2-benzimidazolyl)pyridine

Synthesis and crystal structure of a novel lead coordination polymer, [[Pb3(C8H3O7S)2(C3H7NO)2.5(H2O)]·1.5H2O]n, C47H57N5O38Pb6S4

“…Lead(II) contains the 6s 2 lone-pair, and the absence of crystal field stabilization energy, whichcan causedistortion in coordination sphere [4][5][6][7][8][9],allows for variable coordination numbers. Anumber of polymeric Pb(II) compounds have been structurally characterized, and frequently discussedc onsidering thes tereo-chemical activity of valence shell electron lone pairs [10][11][12][13][14][15][16]. In this paper, we chose the sip (5-sulfo-isophthalate) anion and the Pb(II) cation to construct a coordination polymer.…”

PI and PIII Ions Supported by BZIMPY Ligands

“…However, BZIMPY ligands are more rigid and offer less steric protection to the coordinated element, leaving it more sterically accessible. Complexes of BZIMPY ligands with transition metals, [20][21][22][23] indium, [24] lead, [25][26][27][28][29][30] and silicon [31] have been reported. Recently, we applied BZIMPY ligands to the coordination of group 13 [32] and 14 [33] centers and found strong metal-to-ligand chargetransfer.…”
