摘要：

The title compounds catena-(mu-CrO4-O,O')[M-II(L)]. 5H(2)O (M = Ni-II (1), Cu-II (2); L = 3,14-dimethyl-2,6,13,17-tetraazatricyclo[14,4,0(1.18), 0(7.12)]docosane) are structurally and magnetically characterized. 1 crystallizes in the triclinic system, space group P (1) over bar, a = 10.114(3), b = 11.485(4), c = 13.284(5) Angstrom, alpha = 113.36(4), beta = 100.71(2), gamma = 91.79(2)degrees, V = 1382.4(9) Angstrom(3), Z = 2, R-1 = 0.046, wR(2) = 0.118. 2 crystallizes in the triclinic system, space group P (1) over bar, a = 9.614(2), b = 12.034(2), c = 14.482(3) Angstrom, alpha = 113.63(2), beta = 101.18(1), gamma = 102.45(1)degrees, V = 1423.5(4) Angstrom(3), Z = 2, R-1 = 0.034, wR(2) = 0.064. The crystal structures of chain compounds 1 and 2 revealed an elongated octahedral trans arrangement about each metal(II) ion and showed weak intrachain ferromagnetic interactions with J values of 1.6(1) and 0.10(1) cm(-1), respectively.
