  Bulk single crystals of SrPt3P have been grown for the first time by a
self-flux method at 2 GPa and 1500 {\deg}C using the cubic-anvil, high-pressure
and high-temperature technique. The grown black crystals were found to have
either a plate-like or pillar-like morphology with maximum dimensions of ~ 1 -
0.6 - 0.3 mm3. According to a goniometric study the crystals are elongated in
the ab-plane with the c-axis perpendicular to the plane. The crystal structure
was confirmed by X-ray diffraction (P4/nmm, # 129, Z = 2, a = b = 5.7927(2)
{\AA}, c = 5.3729(2) {\AA} and V = 180.290(11) {\AA}3). Temperature dependent
susceptibility measurements showed a single-phase behaviour and a
superconducting transition temperature of 8.6 K. This value for single crystals
is slightly higher than that previously reported for polycrystalline SrPt3P.
The sharpness of the susceptibility drop ({\Delta}Tc = 0.07 K) supports a high
homogeneity of obtained crystals.
