Synthesis and Crystal Structure of the Flexible Ligand Coordination Polymer Co_3(bpd)_(5.5)(NCS)_6(NH_3)_n·2H_2O (bpd= 1,4-bis(4-pyridyl)-2,3-diaza-1,3-butadiene)

摘要

A novel metal-organic coordination polymer, namely [Co_3(bpd)_(5.5)(NCS)_6(NH_3)]_n·2H_2O (1) (bpd=1,4-bis(4-pyridyl)-2,3-diaza-1,3-butadiene), has been synthesized and characterized by elemental analyses, infrared spectroscopy, and single-crystal X-ray diffraction. Compound 1 presents 2D[3,4,4]-connected 3-nodal net with the point symbol (4~2·6·8~2·10)(4~4·6~2)(8~2·10). In addition, four identical 2D single nets is interlocked with each other in parallel, thus directly leading to the formation of a polycatenated layer(2D→2D).
