Three new molybdate-tellurites, KM(TeO)(MoO)(OH) (M = Ni and Co) and (NH)Cu(TeO)(MoO)(OH), have been successfully synthesized by conventional hydrothermal method. Due to the influence of the Jahn-Teller effect, these compounds crystallize in different space groups of rhombohedral 3̅, monoclinic 2/ and triclinic 1̅ for Ni-, Co-, and Cu-analogues, respectively. The topological arrangements of magnetic ions in these compounds show that deficient capped-kagomé spin-lattices with kagomé positions exhibit different 1/6 depletion. Magnetic and specific heat measurements confirm that KNi(TeO)(MoO)(OH) exhibits a spin-glass behavior at low temperature, while (NH)Cu(TeO)(MoO)(OH) possesses a long-range canted antiferromagnetic ordering with ∼ 10.8 K and further shows a 3/5 magnetization plateau in the magnetization curve at low temperature.
