摘要: Abstract The 31P, 13C, and 195Pt NMR spectra of the compounds {Ph2P(CH2)nPPh2}Pt(CH2)2 were studied compared with acyclic analogue, cis-(Ph2PCH3)2Pt(CH3)2. Comparison structural data showed that irregularities in parameters can be explained on basis existence angle strain for four-membered but not five-membered rings.
