Vanadium doping in yttrium boron-rich boride; YB44Si1.0, is investigated. Vanadium atoms occupy two sites. First, newly discovered site with site occupancy of approximately 3% is far from yttrium atoms and is coordinated "tetrahedrally" by three boron icosahedra and one B12Si3 polyhedron. Another is Si/V mixed-occupation site with site occupancy of ~ 63/6.2 %; it is close to yttrium atoms and is tetrahedrally coordinated by four boron icosahedra. Chemical formula determined from the structure analysis is Y0.96V0.062B41.2Si0.93. Magnetic susceptibility of V-doped YB44Si1.0 was measured from 2 K to 300 K. The vanadium doping in YB44Si1.0 did not result in superconductivity.
