Description

X-ray diffraction analysis of two compounds featuring the composition Co(NH3)6(NpO2C3H2O4)2A·H2O was conducted. Their structures consist of infinite anion chains [NpO2C3H2O4]nn-, cations [Co(NH3)6]3+, anions A (A=OH- or NO3-) and crystallization water molecules. Atoms of Np(V) have hexagonal bipyramidal oxygen surrounding. Coordination capacity of malonate ions equals 6, the ions coordinating simultaneously three NpO2+ dioxocations in the chains

Abstract (Russian)

Проведен рентгеноструктурный анализ двух соединений состава Co(NH3)6(NpO2C3H2O4)2A·H2O, структуры которых построены из беконечных анионных цепочек [NpO2C3H2O4]nn-, катионов [Co(NH3)6]3+, анионов A (A=OH- или NO3-) и молекул кристаллизационной воды. Атомы Np(V) имеют гексагонально-бипирамидальное кислородное окружение. Координационная емкость малонат-ионов равна 6, они одновременно координируют три диоксокатиона NpO2+ в цепочках
