Single crystal of yttrium-zinc intermetallic compound Y<SUB>2</SUB>Zn<SUB>17</SUB> have been synthesized from the elements by means of high-pressure and high-temperature methods in a modified Belt type apparatus (h-BN capsule, 3. 5GPa, 1700°C, and subsequent release of high pressure). Y<SUB>2</SUB>Zn<SUB>17</SUB> crystallizes in the hexagonal system with lattice constants a=8. 9709 (8) Å, c=13. 1386 (8) Å, c/a=1. 4646, space group R 3 m (No. 166), and Z=3. Final residuals after refinement against F<SUP>2</SUP> were R<SUB>1</SUB>=0. 0270, ωR<SUB>2</SUB>=0. 0612 and S=1. 239 for 23 parameters and all 237 unique data. Y<SUB>2</SUB>Zn<SUB>17</SUB> adopts Th<SUB>2</SUB>Zn<SUB>17</SUB>-type structure.
