Thermal expansion coefficients of La_(1-x)Sr_xCrO_3 and reduced La_(1-x)Sr_xCrO_(3-δ) were measured using a push-rod type dilatometer in the temperature range from 100 to 873 K. The thermal expansion coefficient increased and the temperature of structural transition from orthorhombic to rhombohedral decreased with the increase of Sr content. Magnetic transition temperature decreased with the decrease of Cr~(3+) content in La_(1-x)Sr_xCrO_(3-δ).
