Crystal structure of catena-[(bis(O,O′-diethyl dithiophosphato-S,S′)-μ2-1,2-bis(4-pyridylmethylene)hydrazine-N,N′)cadmium(II)], {C20H30CdN4O4P2S4}n

“…The Cd-S1 [2.6671 4 From symmetry, the topology of the resultant onedimensional coordination polymer is linear, as shown in the lower view of the figure, and resembles the literature precedent, {Cd[S 2 P(O-iPr) 2 ] 2 (4-PyAld)}n [7]. By constrast, in the analogous zinc(II) structure to (I), {Zn[S 2 P(OEt) 2 ] 2 (4-PyAld)}n, isolated as a di-acetonitrile solvate, a distorted tetrahedal N 2 S 2 donor set is observed and the resulting coordination polymer has a zigzag topology [9].…”

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

“…By contrast, when n = 3 and R = isopropyl (iPr), a linear chain with a step-ladder topology and an octahedral trans-N 2 S4 donor set is found [7]. In the case when n = 4, and R = Et [8] and cyclohexyl (Cy) [9], zigzag coordination polymers are found but with tetrahedral N 2 S 2 and octahedral cis-N 2 S4 donor sets, respectively. A greater homogeneity in the coordination polymers formed by cadmium(II) is noted in that trans-N 2 S4 donor sets are found.…”
