Two novel compounds Bi2Ni(SeO3)(4) and Bi2Ni(SeO3)(4).2H(2)O were synthesized by hydrothermal method and their crystal structures were solved via single crystal diffraction. The magnetic Ni2+ ions are arranged in a cubic-like mode, while both Bi2Ni(SeO3)(4) and Bi2Ni(SeO3)(4).2H(2)O exhibit magnetic frustration. Notably, the magnetic measurement shows that Bi2Ni(SeO3)(4) has a Weiss temperature of -21 K but does not exhibit any magnetic ordering down to 2 K. This study provides a scheme for realizing magnetic frustration with compounds of cubic like magnetic lattice. In the future, it is intriguing to uncover the ground magnetic state of Bi2Ni(SeO3)(4).
