We have synthesized CuFeAs, a new iron-pnictide compound with a layeredtetragonal Cu2Sb type structure (space group P4/nmm: a = b = 3.7442(2) {\AA}and c = 5.8925(4) {\AA}) that is identical to that of 111-type iron-basedsuperconductors. Our measurements suggest that in low applied magnetic field itundergoes an antiferromagnetic transition below TN ~ 9 K. When compared withthe ground state of CuFeSb, recently reported 111-type ferromagnetic material(TC ~ 375 K), it has important implication with regard to the nature of Fe-Femagnetic interaction in Fe-As materials. CuFeAs does not exhibitsuperconductivity down to 2 K.
