摘要：

The preparation, crystal structure, and infrared spectrum are reported for the new compound U(H2PO2)4. The coordination geometry of uranium is approximately described as a square anti-prism. The four independent hypophosphite groups which are bonded to each uranium atom also serve as bridging groups in linking the uranium centers into a three-dimensional network. The internal H2PO2- vibrational modes in the infrared spectrum of U(H2PO2)4 show unit-cell group couplings, particularly for the P-H stretching vibrations, making the spectrum distinctly different from that of the simple bidentate non-bridging H2PO2- ion in KH2PO2 and VO(H2PO2) . H2O.
