  Single crystals of a new silver and-cobalt based vanadate AgCo2V3O10 were
grown from a melted mixture. The crystal structure determination reveals that
this new vanadate crystallizes in triclinic system with space group P-1. The
structure of the titled compound is constructed from CoO6octahedra and VO4
tetrahedra sharing edges and vertices leading to an open three-dimensional
framework delimiting tunnels along [001], where the Ag cations are located. The
bands observed in Raman spectrum were assigned to corresponding vibrations of
the VO4 groups. DC and AC magnetization (susceptibility) measurements revealed
the spin-glass (SG) -type transition below a frequency-independent temperature
Tf(H) that is nearly independent on the applied magnetic field. Magnetic field
H> 10 kOe induces the spin glass antiferromagnet. These observations brings
AgCo2V3O10 into the class of geometrically frustrated magnetic systems.
