Synchrotron X-ray diffraction studies of Ca1-xLaxFeAs2 with monovalent arsenic zigzag chain layers are presented. While the crystal twins appear in all samples for the nominal composition of x = 0.25, we successfully obtained the samples without crystal twins for the nominal composition of x = 0.17. We present the structural parameters obtained using the synchrotron X-ray diffraction data and physical properties for the samples with x = 0.17. We further discuss the tactics for exploring novel 112-type iron arsenides without arsenic zigzag chains.
