以层状三元硫系化合物ta2pds6为原料，通过插入钠或钾成功合成了两种新相。MTa2PdS6（M = Na， K）在单斜空间中结晶。12), Z = 2,与晶格parametersa = 8.1366 (7), b = 3.2876 (1) A, c = 15.3279(3),β= 97.407(2)°NaTa2PdS6,安达= 8.3845 (3)A, b = 3.2955 (1) A, c = 16.7416(8),β= 86.339(3)°KTa2PdS6而言。插入后，母相的一般结构保持不变，Na和K的插入物分别增加了17.3%和33.2%的细胞体积。SQUID磁强分析表明，这两种插层都是净抗磁铁，但由于部分带填充增加了泡利顺磁分量，导致ta2pds6的磁化率显著降低。
Two new phases derived from the layered ternary chalcogenide Ta2PdS6have been successfully synthesised via the intercalation of sodium or potassium.MTa2PdS6(M= Na, K) crystallise in monoclinic space groupI2/m(No. 12),Z= 2, with lattice parametersa= 8.1366(7) Å,b= 3.2876(1) Å,c= 15.3279(3) Å, β = 97.407(2)° for NaTa2PdS6, anda= 8.3845(3) Å,b= 3.2955(1) Å,c= 16.7416(8) Å, β = 86.339(3)° in the case of KTa2PdS6. The general structure of the parent phase is retained upon intercalation, with increased unit cell volumes of 17.3% and 33.2% for the Na and K intercalates respectively. SQUID magnetometry shows that both intercalates are net diamagnets, but shows a significant reduction of magnetic susceptibility from Ta2PdS6due to the increase in a Pauli paramagnetic component due to partial band filling.
