The reaction of SiW~9O^1^0^-~3~4 and GeW~9O^1^0^-~3~4 with metal cations leads to trisubstituted Keggin, sandwich, and dimer types of complexes, respectively. The characteristic patterns of ^1^8^3W NMR chemical shifts for the substituted derivatives of lacunary XW ~9O^1^0^-~3~4(X=Si,Ge) are summarized.
