摘要:
The structure of tri-mu-acetato-diaqua-mu-nitrato-dicalcium [Ca-2(CH3COO)(3)(NO3)(H2O)(2)](n), is shown to consist of infinite O-bridged double-stranded calcium chains crosslinked both by bridging anions and by hydrogen bonding to form a three-dimensional polymer. Both the independent Ca centres are eight-coordinate.
