Abstract

The synthesis and characterization of the neutral uranylisocyanate UO(2)(NCO)(2)(OP(NMe(2))(3))(2) [crystal data: monoclinic, P2(1)/c, a = 8.512(2) A, b = 10.931(2) A, c = 14.329(3) A, beta = 103.923(3) degrees , V = 1294.0(4) A(3), Z = 2] and isocyanato uranate (Et(4)N)(6)(UO(2))(2)(NCO)(5)O x 2CH(3)CN x H(2)O [crystal data: monoclinic, P2(1)/c, a = 17.2787(2) A, b = 15.560(1) A, c = 32.7619(4) A, beta = 94.0849(5) degrees , V = 8786.5(2) A(3), Z = 4] are reported. Not only are these compounds the first unambiguously characterized uranium isocyanates regardless of the oxidation state for uranium, but they are also the first structurally characterized actinide isocyanates. Both compounds show coordination of the OCN moiety through nitrogen to uranium and were characterized using IR and (1)H, (13)C, (14)N, and (31)P NMR spectroscopy and X-ray diffraction.

摘要

报道了中性异氰酸铀酰UO(2)(NCO)(2)(OP(NMe(2))(3))(2) [晶体数据：单斜晶系，P2(1)/c，a = 8.512(2) Å，b = 10.931(2) Å，c = 14.329(3) Å，β = 103.923(3)°，V = 1294.0(4) Å(3)，Z = 2] 和异氰酸铀酸盐(Et(4)N)(6)(UO(2))(2)(NCO)(5)O·2CH(3)CN·H(2)O [晶体数据：单斜晶系，P2(1)/c，a = 17.2787(2) Å，b = 15.560(1) Å，c = 32.7619(4) Å，β = 94.0849(5)°，V = 8786.5(2) Å(3)，Z = 4]。这些化合物不仅是首批明确表征的铀异氰酸盐，无论铀的氧化态如何，而且它们也是首批通过结构表征的锕系异氰酸盐。两种化合物均显示出OCN基团通过氮与铀配位，并使用红外光谱、(1)H、(13)C、(14)N和(31)P核磁共振光谱以及X射线衍射进行了表征。
