Magnetic Behavior Control in Niccolite Structural Metal ...
By changing template cation but introducing trivalent iron ions in the known niccolite structural metal formate frameworks, three complexes formulated [NH2(CH3)2][FeIIIMII(HCOO)6] (M = Fe for 1, Mn for 2, and Co for 3) were synthesized and magnetically characterized. The variation in the compositions of the complexes leads to three different complexes: mixedvalent complex 1, heterometallic ...Get Price
Maucherite: Properties and Occurrences Assignment Point
Properties. It is a nickel arsenide mineral with chemical composition approximating, assigned to the group of sulfide minerals. It crystallizes in the tetragonal crystal system.

Nickel (Ni) Properties, Applications
Nickel (Ni) was discovered in 1751 in Stockholm, Sweden by Cronstedt from the ore kupfernickel (niccolite). It is a silverwhite metal and mainly occurs in the arsenic and sulfide ores. It is extracted by roasting to NiO and then reducing with carbon.Get Price
