摘      要：Four new deficient compounds in the R6B2C2QI4 family, LasCaSn2.75S4 1, Y6A10.67Ge2S14 2, Er5.33Si4S14 3 and Er4Ge4SI4 4, have been obtained via a precursor/flux method. Single-crystal analysis indicated that their crystal structures consist of three types of building blocks： RS7 （R = La/Ca for 1, R = Y for 2, R = Er for 3 and 4） mono-triangonal prism, CS6 （C = A1 for 1, C = Sn（2） for 2, C = Si（2） for 3, C = Ge（2） for 4） octahedron, and BS4 （B = Si for 1, B = Sn（1） for 2, B = Si（1） for 3, B = Ge（1） for 4） tetrahedron, as any other compounds belong to the R6B2C2Q14 family.
