In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Structure of some uranium(IV) chelates in solution, published in 1969, which mentions a compound: 18362-64-6, mainly applied to uranium chelates structure; acetylacetinato uraniums, SDS of cas: 18362-64-6.
N.M.R. spectral data of UL4 [HL = RC(O)CH2C(O)R, where R = Me, Et, iso-Pr, tert-Bu] and UL4-xL1x [x = 1-3, R in HL = tert-Bu, and HL1 = HL (R = Et)] indicate a less sym. structure for the compounds than a D2 sq. antiprism or a D2d triangular dodecahedron.
Compounds in my other articles are similar to this one(2,6-Dimethyl-3,5-heptanedione)SDS of cas: 18362-64-6, you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
