摘要: Abstract Three new mercury(II) coordination polymers, [Hg2(μ-bpa)(μ-SCN)2(μ-CH3COO)2]n (1), [Hg2(μ-4-bpdb)1.5(μ-CH3COO)(μ1,1- SCN)(μ1,3-SCN)(SCN)]n · CH3CN (2) and [Hg(μ-3-bpdb)(CH3COO)2]n (3) {(bpa = 1,2-bis(4-pyridyl)ethane, 4-bpdb) = 1,4-bis(4-pyridyl)-2,3-diaza-1,3-butadiene 3-bpdb = 1,4-bis(3-pyridyl)-2,3-diaza-1,3-butadiene, have been synthesized characterized by CHN elemental analysis IR spectroscopy. The single crystal X-ray data show the compound 1 is two-dimensional polymer as a result of simultaneously bridging 1,2-bis(4-pyridyl)ethane, acetate thiocyanate ligands. single-crystal 2 that complex to be polymer, one Hg atoms has four-coordinate them seven-coordinate. SCN− anions three different modes with terminal, μ1,1-bridge μ1,3-bridge fashions. structural studies 3 structure may considered one-dimensional consisting linear chains formed 3-bpdb ligand. thermal stabilities these compounds were studied gravimetric (TG) differential analyses (DTA).
