%X The components of the elastic constant matrix of monoclinic caesium dihydrogen phosphate (CDP) have been determined using ultrasonic velocity measurements to be Cl1 = 28· 83 ± 0 '43, C22 = 26·67 ± O· 37, C33 = 65 ·45 ± 0'48, C44 = 8 .1O± 0,15, Css = 5 ·20± 0,24, C66 = 9·17 ± 0,22, C12 = 1l'4±3'6, C13 = 42·87±1·58, CIS = 5'13±0'67, C23 = 14·5±4·4, C 2S = 8'4±4'3, C3S = 7·50±0·81 and C46 = -2·25±0·31 GPa. Calculations of the velocity surfaces, ray directions, Young's modulus surfaces and linear compressibility show marked elastic anisotropy, which has been correlated with the chain and layer-like structure of CDP.
