Crystal structure of catena-poly[(bis(O,O′-diethyl dithiophosphato-κ2 S,S′)-μ2-1,2-bis(3-pyridylmethylene)hydrazine-κ2 N:N′)cadmium(II)], {C20H30CdN4O4P2S4}n

“…However, it should be noted that zero-dimensional species are sometimes isolated when polymeric species might otherwise be anticipated. An example is seen in the structure of binuclear {Zn[S 2 P(O-iPr) 2 ] 2 } 2 (4-PyAld) [15]. More intriguing are monodentate (terminal) modes of coordination of the 4-PyAld ligand have been noted in some dithiocarbamate ( − S 2 CNR 2 ) derivatives, namely Zn[S 2 CN(Me)CH 2 CH 2 OH] 2 (4-PyAld), with a square-pyramidal geometry based on a NS4 donor set [16] and Cd[S 2 CN(nPr)CH 2 CH 2 OH] 2 (4-PyAld) 2 [n-propyl = nPr], with a trans-N 2 S4 donor set [17].…”
